[libvirt] [PATCH v2] maint: Update to latest gnulib

[Eric Blake]

From: Michal Privoznik <mprivozn at redhat.com>

Unfortunately, since gnulib's commit of 2c5d558745 there's an
unused parameter to stat_time_normalize() function which gnulib
developers don't want to fix yet [1]. Therefore, we have to work
around it by temporarily providing a downstream patch.

[eblake: use gnulib local diff, instead of #pragma]

v2: perhaps nicer than Michal's original suggestion, but I'd still
wait another day or two to see if my arguments on the upstream
gnulib thread can instead give us a better submodule commit to
update to that avoids the problem altogether.
