[613/906] window_cocoa: fix segfault with gst-launch-1.0 -e ... and sending SIGINT (Ctrl-C)

GNUstep has a signal handler for SIGINT which runs in the main thread.
However that thread has never been 'registered' with GNUstep so
the autorelease magic of objective-c causes a segfault from accessing
a null NSThread object somewhere deep in GNUstep.
