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.
* tests/chtype.at, tests/comprec.at, tests/exclude06.at:
* tests/extrac01.at, tests/extrac03.at, tests/extrac05.at:
* tests/extrac06.at, tests/extrac08.at, tests/extrac13.at:
* tests/extrac14.at, tests/incr01.at, tests/incr03.at, tests/link01.at:
* tests/multiv01.at, tests/multiv02.at, tests/multiv03.at:
* tests/pipe.at, tests/rename02.at, tests/rename03.at:
* tests/rename05.at, tests/same-order01.at, tests/same-order02.at:
* tests/sparse01.at:
Likewise.

# Problem: If a member with link count > 2 was stored in the archive twice,
# previous versions of tar were not able to extract it, since they
# were trying to link the file to itself, which always failed and
# lead to removing the already extracted copy. This script tests
# the workaround by Paul Eggert that leaves the extracted copy
# untouched.
