media-libs/cogl: Apply upstream fixes, also fix cogl not working at all with fglrx drivers, we need to apply the fix conditionally until someone figures out how to properly check for fglrx presence for the patch (#567168, upstream bug #756306, thanks to Olcay for reporting and testing this).

+Subject: kms-winsys: don't wait for a flip when page flipping fails
+
+If we get EACCES from drmPageFlip we're not going to get
+a flip event and shouldn't wait for one.
+
+This commit changes the EACCES path to silently ignore the
+failed flip request and just clean up the fb.
