Sukadev Bhattiprolu 09bca05c90 SEND_SIG_NOINFO: masquerade si_pid when crossing pid-ns boundary
For SEND_SIG_NOINFO, si_pid is currently set to the pid of sender
in sender's active pid namespace. But if the receiver is in a
Eg: when parent sends the 'pdeath_signal' to a child that is in
a descendant pid namespace, we should set si_pid 0.
