[libvirt] fix two "make syntax-check" failures

[Jim Meyering]

Mark McLoughlin pointed out this failure:

    ChangeLog-old: if (foo) free (foo)
    ChangeLog-old: if (foo != NULL) free (foo)
    maint.mk: found useless "if" before "free" above
    make: *** [sc_avoid_if_before_free] Error 1

Here's the other:

+cfg.mk
 qemud/qemud.c
 qemud/remote.c
 src/bridge.c
maint.mk: you have changed the set of files with translatable diagnostics;
 apply the above patch

I had fixed the latter in gnulib (now that main.mk comes
from there), but had forgotten to tell libvirt to use
the latest version of gnulib, in order to get that fix.
To do that, I ran "git syncsub" (where syncsub is an alias:
syncsub = submodule foreach git pull origin master)
then git commit -a.

Here are the two patches I'm about to push:

Subject: [PATCH 2/2] build: update from gnulib, for latest maint.mk

* gnulib: Update submodule to latest.
This fixes the make syntax-check failure whereby sc_po_check
would complain about cfg.mk.
