[new release] irmin project (3.4.3)

[icristescu]

CHANGES:

Fixed

• irmin-pack
  • Fix read-only opening flags of mapping for read-only opening of stores that
    do not have read-write rights on the files. (irmin-pack: Fix mmap RO opening flags mirage/irmin#2121, @Ngoguey42)

[kit-ty-kate]

Why also adding this restrictions to the other packages? Only the tests for those were failing and this can be ignored or disabled at test level

[icristescu]

@kit-ty-kate I moved the os restriction on the tests only.

The error in the CI seems to me unrelated to irmin, so maybe this can be merged? Let me know if you think I need to fix something on irmin side. Thanks!

Merging this as the remaining errors do not seem related to the PR. @icristescu could you open issues so that these remaining errors are not forgotten? Thanks

[icristescu]

I think the issue with the tests should be solved by mirage/irmin#2127. It is an issue with irmin packages after all, I'll open a PR to fix the current release.
