[S390] duplicate SIGTRAP on signal delivery.
The code in do_signal sets the TIF_SINGLE_STEP bit and calls tracehook_signal_handler after the signal frame has been set up. This causes two SIGTRAP signals to be delivered to the tracer. Stop setting the TIF_SINGLE_STEP bit in do_signal to get the correct number of SIGTRAPs. Signed-off-by: Martin Schwidefsky <email@example.com>
