signals: sys_ssetmask() uses uninitialized newmask
Commit 77097ae503b1 ("most of set_current_blocked() callers want
SIGKILL/SIGSTOP removed from set") removed the initialization of newmask
by accident, causing ltp to complain like this:
ssetmask01 1 TFAIL : sgetmask() failed: TEST_ERRNO=???(0): Success
Restore the proper initialization.
