Could these branches be removed from all eleven tests? Linux 7.2 uses
scoped_timer_get_or_fail() to return -EINVAL for invalid timer IDs in
timer_gettime(), timer_getoverrun(), timer_settime(), and timer_delete().
The installed man pages document the same EINVAL result.

More directly, every pre-patch test reports errno == EINVAL and returns
PTS_PASS when built and run on Linux. The platform check therefore replaces
working coverage with PTS_UNSUPPORTED, and the quoted runtime message is not
accurate.

Verdict - Needs revision
