landlock: Clarify BUILD_BUG_ON check in scoping logic 
The BUILD_BUG_ON check in domain_is_scoped() and
unmask_scoped_access() should check that the loop that counts down
client_layer finishes.  We therefore check that the numbers
LANDLOCK_MAX_NUM_LAYERS-1 and -1 are both representable by that
integer.  If they are representable, the numbers in between are
representable too, and the loop finishes.
