MFC r328266:
mlock(2): correct documentation for error conditions.
The man page is years out of date regarding errors. Our implementation _does_
allow unaligned addresses, and it _does_not_ check for negative lengths,
because the length is unsigned. It checks for overflow instead.
Update the tests accordingly.
