Subject: [PATCH] Switch back to matching `target_os` rather than
 `target_vendor`

`ctest` is very particular about this and the current configuration,
though working most of the time, seems to cause occasional CI errors
that can't easily be explained or mitigated. Switch back to matching all
Apple `target_os` options until `ctest` is fixed.

(backport <https://github.com/rust-lang/libc/pull/4282>)
(cherry picked from commit a986f81dbc23bf669fdecd81a74b6ae3999cb8c8)
