Paul Eggert 502abd93bd tests: port to NFS file servers with clock skew
Several of the tests assumed that a newly created file cannot
have a time stamp dated in the future.  This assumption is not
true when files are served by a remote host whose clock is
slightly in advance of ours.  Fix the problems that I observed
when running "make check" a couple of times on such a server.

* tests/backup01.at: Use --warning=no-timestamp to suppress
clock-skew warnings.

Likewise.

# Description:
# When extracting, tar (<1.22) sometimes renamed a backup back to the
# original name (overwriting the newly-extracted file) for no good reason.
