    futex: Add sys_futex_wait()

    To complement sys_futex_waitv()/wake(), add sys_futex_wait(). This
    syscall implements what was previously known as FUTEX_WAIT_BITSET
    except it uses 'unsigned long' for the value and bitmask arguments,
    takes timespec and clockid_t arguments for the absolute timeout and
    uses FUTEX2 flags.

    The 'unsigned long' allows FUTEX2_SIZE_U64 on 64bit platforms.
