win32: use glib gpoll if glib >= 2.50 

A fix has been committed in upstream glib commit
210a9796f78eb90f76f1bd6a304e9fea05e97617.
(See also related bug https://bugzilla.gnome.org/show_bug.cgi?id=764415)

It is desirable to use the glib version instead of qemu copy, since it
provides more debugging facilities (G_MAIN_POLL_DEBUG etc), and
hopefully has a better maintainance. Hopefully, we can drop the qemu
copy in a few years.
