The licenses of the strchrnul module and its dependent, rawmemchr,
have been relaxed to LGPLv2+, so to get that updated in gnulib,
I've added a preceding commit that adjusts libvirt's .gnulib
submodule to use latest commit from upstream gnulib.

With that, autogen.sh notices the change and automatically
runs ./bootstrap.

I confirmed that "make check" passes all tests.
