Remove mlockall alert handler
The probability of such errors is negligible now because we lock
unconditionally. So we can remove the machinery that used to report such
bugs to the user. The nucleus will still raise a signal if userspace
willingly unlocked the memory - it will get what it deserves (an
untranslated signal).
