Subject: [PATCH] rustdoc: Use `unix_sigpipe` instead of
 `rustc_driver::set_sigpipe_handler`

Start using `unix_sigpipe` instead of
`rustc_driver::set_sigpipe_handler`.

After this has been merged, we can completely remove
`rustc_driver::set_sigpipe_handler`.

Verification of this change
---------------------------

1. Remove `#[unix_sigpipe = "sig_dfl"]`
1. Run `./x.py build`
1. Run `./build/aarch64-apple-darwin/stage1/bin/rustdoc --help | false`
1. Observe ICE
1. Add back `#[unix_sigpipe = "sig_dfl"]`
1. Run `./x.py build`
1. Run `./build/aarch64-apple-darwin/stage1/bin/rustdoc --help | false`
1. Observe ICE fixed
