Subject: paxutils: use POSIX interface for file time-setting

This is a minor cleanup to use the POSIX.1-2008 interface for
setting file time stamps to nanosecond resolution, rather than
the pre-2008 gnulib interface.  On older hosts, it falls back
on gnulib's implementation of the POSIX interface.
* configure.ac: Don't check for utimes; it's not used.
* gnulib.modules: Add utimensat.
* tests/genfile.c: Don't include utimens.h.
(exec_checkpoint): Use POSIX utimensat function, not utimens.
