ui/gtk: don't pass on win keys without keyboard grab

Without keyboard grab Windows currently handles the two win keys
and the key events are also sent to the guest. This is undesir-
able. Only one program should handle key events. This patch ap-
plies commit c68f74b02e "win32: do not handle win keys when the
keyboard is not grabbed" from project spice-gtk to ui/gtk.c to
fix this problem.
