Subject: [PATCH] Avoid pthread_sigmask on Win32 platforms

Win32 doesn't have a concept of signal masks so disable that
code. It is unclear how SIGINT is delivered (if at all) on
Win32, so this might further work to provide an alternative
to pthread_sigmask

* tools/virsh.c: Avoid pthread_sigmask on Win32
