login: never send signals to init

If the signal handler is triggered after a failed fork attempt, then
child_pid will be -1. This in turn leads to a positive test and a
subsequent call of kill(1, signal). If signal was SIGTERM, then there
will be also another kill(1, SIGHUP) call.

Test explicitly for a positive child_pid value to prevent these cases.
