 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.

Comment(by erikd):

 The patch has been validated on x86-64 linux and powerpc-linux. It also
 means the Qemu/Arm build works much better (there is still at least one
 bug in Qemu though).

 @simonmar : If you'd like, I can commit this directly, but since I was
 messing with the RTS I thought I better run this past you first.
