test-stat-time fails on AFS?

Hi.  We got a bug report about a gnulib self-test failure:

https://gitlab.com/oath-toolkit/oath-toolkit/-/issues/30

Summarizing, this is the failure:

test-stat-time.c:186: assertion 'statinfo[2].st_mtime < statinfo[1].st_ctime || (statinfo[2].st_mtime == statinfo[1].st_ctime && (get_stat_mtime_ns (&statinfo[2]) < get_stat_ctime_ns (&statinfo[1])))' failed

The user is building it on an AFS file system, which most likely
explains the failure (although that has to be confirmed).  While the
explanation may be that AFS is not providing POSIX-semantics for the
file system, I think failing a self-test for this reason is too strong:
it could print an error message, or SKIP the test.  Thoughts?

Since the nap () business in that test is a heuristic and there's a good 
chance it's stricter than what POSIX requires, this sounds OK to me.
