Target.killall: catch TargetError on individual kills

Browse Source 
killall() is implemented by discovering all PIDs who's name matches the
specified process, and then sending individual kills for each PID. If a
PID no longer exists by the time the kill is sent (e.g. if it was a
child of one of the previously killed PIDs), this will result in a
TargetError, which for the purposes of killall() should be ignored.
