sparse: define __must_be_array() for __CHECKER__
commit c5e631cf65f ("ARRAY_SIZE: check for type") added __must_be_array().
But sparse can't parse this gcc extention.
Now make C=2 makes following sparse errors a lot.
kernel/futex.c:2699:25: error: No right hand side of '+'-expression
Because __must_be_array() is used for ARRAY_SIZE() macro and it is
used very widely.
This patch fixes it.
