Subject: Update futex test in accordance with kernel's v4.15-rc7-202-gfbe0e83
Patch-mainline: yes
References: fix new kernels

* futex.c (VALP, VALP_PR, VAL2P, VAL2P_PR): New macro definitions.
(main): Allow EINVAL on *REQUEUE* checks with VAL/VAL2 with higher bit
being set, check that the existing behaviour preserved with VALP/VAL2P
where higher bit is unset.
