efl thread signal masks - fix up for various threads manually created

so xine module plus 2 eina dbug threads didnt set up signal
blocking/masks correctly. xine use ssigprocmask not pthread_sigmask
and the other 2 didnt even bother at all. fix this so these threads
all block most of these commnly caught signals so these threads never
get them
