maint: update to latest gnulib

Upstream gnulib determined that we were needlessly compiling in
gnulib's regex instead of glibc's when targetting new-enough glibc,
because the m4 test was being too strict in requiring a particular
answer to undefined behavior.

* .gnulib: Update to latest, for regex.
(cherry picked from commit 842432390b)

Cherry picked because I hit a failure of test-regex when swapping
between incremental builds of libvirt.git master then v1.0.4-maint.
