parisc: fix tracing of signals

Mike Frysinger pointed out that calling tracehook_signal_handler with
stepping=0 missed testing the thread flags, resulting in not calling
ptrace_notify. Fix this by testing if we're single stepping or branch
stepping and setting the flag accordingly.

Tested, seems to work.
