xfree86: Convert some xf86BlockSIGIO to OsBlockSignals

The DDC1 and int10 code are blocking SIGIO to get some assurance that
their usleep() calls take as long as they expect.  That's a good start
but you really want to be blocking more than just SIGIO, SIGALRM too at

At this point, except for SIGIO handler setup itself, BlockSIGIO really
means "block input events".
