Update the musl headers in CI to use alpine-linux instead of sabotage-linux.
Alpine also uses musl but follows the linux stable releases, providing more up-to-date headers.

Now that we have Linux 6.6 we can clean up some of the test exceptions.
Not all of them can be removed, so the comments are updated if needed.

(cherry picked from commit 55f9451)

Signed-off-by: Trevor Gross <tmgross@umich.edu>
This bug was fixed in e9abac9 ("Set CLONE_CLEAR_SIGHAND and
CLONE_INTO_CGROUP to a large enough type") and these checks were removed
in acc75e7 ("ci: update musl headers to 6.6"). However, we cannot
backport the fix, so add back the override here.
(backport <rust-lang#4128>)
(cherry picked from commit 38318cd)
Add `group_imports` and `import_granularity` to our rustfmt config.
These values are the same as in rust-lang/rust.

(backport <rust-lang#4136>)
(cherry picked from commit 0456dcb)
`libc-0.2` version of 236e069 from [1]
(not a direct cherry pick).

[1]: rust-lang#4136
The statx system call and corresponding constants are defined by the
Linux kernel and don't depend on the libc or architecture. The only
difference is whether a libc exports the statx syscall wrapper or not.

We can thus unify the statx definitions for all Linux "like" platforms:
GNU (glibc), Android (bionic), and (in a later commit) musl.

Plain u64 (or uint64_t in C) can't be used for the statx fields because
bionic defines them as __u64, and provides incompatible definitions of
uint64_t and __u64.

This API appears to not be available in more recent MacOS SDKs, and
there aren't any functions that use it. Since this hasn't yet made it
into a release, remove it.

Link: rust-lang#4022

(backport <rust-lang#4137>)
(cherry picked from commit e87acba)
This moves similar types together (e.g. statfs and statfs64) so removing
them is cleaner.

(backport <rust-lang#3261>)
(cherry picked from commit 6c0952e)
Musl provides a single definition for `siginfo_t` [1] with the order of
`si_code` and `si_errno` controlled by `__SI_SWAP_ERRNO_CODE`. This is
only set on mips (both 32- and 64-bit).

[1]: https://github.com/kraj/musl/blob/ffb23aef7b5339b8c3234f4c6a93c488dc873919/include/signal.h#L99-L147

[ extracted from "Remove all redundant definitions in musl backend", add
  context to the commit message - Trevor ]

(backport <rust-lang#3261>)
(cherry picked from commit e1ff5d6)
`statvfs` already exists in `musl/mod.rs`. Use that were possible and
move a common version of `statvfs64` there.

[ reduce this patch to only cover statvfs*, leaving statfs as a separate
  change - Trevor ]

(backport <rust-lang#3261>)
(cherry picked from commit adcc84d)
Only mips uses a special statfs(64)

[ squash "Use `#[cfg]` blocks to special-case statfs on mips", change
  this patch to only cover statfs and statfs64, include part of "Remove
  new redundant definitions" - Trevor ]

(backport <rust-lang#3261>)
(cherry picked from commit fb7785a)
These types are redundant as they are exported from higher-level
modules.

[ move some non-statfs fixups here from other commits in the series, add
  context to the commmit message - Trevor ]

(backport <rust-lang#3261>)

Note to self, gh pr list --state merged --label stable-nominated --json 'mergedAt,number' --jq 'sort_by(.mergedAt)' --limit 400 | jq '.[].number' | xargs -IPR_NUM gh pr view PR_NUM --json 'author,url, title,mergedAt,number,commits' --jq '.login = .author.login | .author = .author.name | .commits = (.commits | map({oid, messageHeadline})) | .msg = "(backport <" + .url + ">)"' is great for finding PRs that need a backport
