Damien Neil fb0c27c514 os: do not follow dangling symlinks in Root when O_CREATE|O_EXCL on AIX
OpenFile with O_CREATE|O_EXCL should not follow dangling symlinks.
On AIX it does, because AIX's openat(2) apparently returns ELOOP
in this case. Most Unices return EEXIST.

Ensure that we never follow symlinks in the final component of
the path when opening a file with O_CREATE|O_EXCL.

Fixes #73924
