rts: Ignore signal before deleting timer. Fixes #7303.
Was getting an ocassional hang or segfault when building GHC in a
Qemu user space emulation of ARM. Turned out that the ITIMER_SIGNAL
was being delivered *after* the call to timer_delete(). Setting the
signal to SIG_IGN before deleting the timer solves the problem.
