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. Bug: 16005022 Change-Id: I0548003f4fc3b1889a6859091e603ead4a9b0607
