Fix pthread_sigmask check for mingw32 without winpthreads

On Fedora 19 and older the pthreads impl provided with
mingw does not have any pthread_sigmask impl at all. The
configure.ac check was not distinguishing this scenario
from that of a broken pthread_sigmask impl, so was
mistakenly enabling the libvirt workaround even when it
was not needed. This in turn conflicted with the gnulib
provided pthread_sigmask impl.
