AIX: Fix the types of 'struct stat'/'struct stat64' fields 'st_*tim'

[xingxue-ibm]

Description

On AIX, when _ALL_SOURCE is defined, the st_*tim fields in struct stat/struct stat64 use struct st_timespec, whereas under POSIX, they use struct timespec. This patch updates the type to align with the POSIX declaration.

Checklist

• Relevant tests in libc-test/semver have been updated
• No placeholder or unstable values like *LAST or *MAX are
  included (see #3131)
• Tested locally (cd libc-test && cargo test --target mytarget);
  especially relevant for platforms that may not be checked in CI

Would it make sense to add this as a define at https://github.com/xingxue-ibm/libc/blob/a861a0b0cb16dd0cfcb642c3d294fba754cf6df2/libc-test/build.rs#L5470?

Yeah, I tried that before. Defining _XOPEN_SOURCE excludes quite a few non-POSIX functions.

SGTM then. Wrote up #4598 in case it helps.

Thanks!
