Remove incorrect check for sa_mask in signal chaining
This removes an incorrect check using the sa_mask field of the
sigaction structure when chaining to a user's signal handler.
The check prevented a user's handler being called when sa_mask
was set.
Thanks to primiano@ for the excellent bug report.
