futex: avoid printing val when it is not used by the futex command

Browse Source 
This is analogous to timeout argument omitting in FUTEX_WAKE_BITSET
command.

* futex.c (SYS_FUNC(futex)): Remove common printing of val argument.
Add printing of val argument for all futex commands except
FUTEX_LOCK_PI, FUTEX_UNLOCK_PI, and FUTEX_TRYLOCK_PI.
