[libvirt] [PATCH] build: avoid test warnings on mingw

[Eric Blake]

* .gnulib: Update to latest, for getaddrinfo fixes.
Reported by Matthias Bolte.
---

As promised, I've done the gnulib side of the mingw cleanups
affecting the issues Matthias found with 0.9.1-rc1.

Oh, and now that gnulib getcwd-lgpl exists, we could use it
to fix our uses of getcwd(NULL,0), followup coming later.

* .gnulib 7d06b32...74175b9 (29):
