[PATCH 1/8] Fix FUTEX_WAKE_OP compare function mask

[Eugene Syromyatnikov]

* futex.c (SYS_FUNC(futex)) <FUTEX_WAKE_OP>: compare function does not
  have FUTEX_OP_OPARG_SHIFT flag and occupies 4 bits from bit 24 to bit
  27, as per both initial and current (v4.7) kernel implementations, so
  bring futex parser in accordance with this.
