[libvirt] [PATCH] Allow bootstrap to build gnulib from local git source if $GNULIB_SRCDIR is non-empty.

[Prerna Saxena]

'bootstrap' script clones the .gnulib submodule from upstream git 
sources only (provided in .gitmodules), irrespective of whether 
$GNULIB_SRCDIR is provided.
This patch allows gnulib git sources provided by $GNULIB_SRCDIR to be 
used for adding the gnulib submodule.

Subject: [PATCH] [Fix] Do not pull from upstream git repo if local copy 
of git sources is provided.
Presently, gnulib gets cloned from git://git.sv.gnu.org/gnulib.git 
irrespective of local sources in $GNULIB_SRCDIR.
