SIGEV_THREAD timers: fix fatal signal if internal SIGTIMER becomes unblocked
commit 6ae2568bc2367b4d47e0ea1cb043fd56e697912f introduced a fatal
signal condition if the internal timer signal used for SIGEV_THREAD
timers is unblocked. this can happen whenever the application alters
the signal mask with SIG_SETMASK, since sigset_t objects never include
the bits used for implementation-internal signals.
this patch effectively reverts the breakage by adding back a no-op
signal handler.
overruns will not be accounted if the timer signal becomes unblocked,
but POSIX does not specify them except for SIGEV_SIGNAL timers anyway.
