[libvirt] [PATCH] build: fix virBufferVasprintf on mingw

[Eric Blake]

Gnulib documents that mingw [v]snprintf is broken (it returns -1
on out-of-space, instead of the count of what would have been
printed); but while we were using the snprintf wrapper, we had
not yet been using the vsnprintf wrapper.

* bootstrap.conf (gnulib_modules): Add vsnprintf.
