[LTP] [PATCH V3] syscalls/timer_settime01: Make sure the timer fires

[Cyril Hrubis <chrubis@suse.cz>]

Hi!
Pushed with minor changes, thanks.

Among other fixes I've moved the signal check from the signal handler to
the clear_signal() function, since the tst_res() function is not
signal-async-safe...
