touch: update to latest gnulib to fix Solaris 10 touch segfault

* gnulib: Update to latest, to address http://debbugs.gnu.org/8230.
When built on Solaris 9 and run on Solaris 10, touch would segfault.
Reported by Ben Walton.
* bootstrap: Update from gnulib.
* tests/init.sh: Likewise.
* NEWS (Bug fixes): Mention this.
