linux-user/syscall.c: handle FUTEX_WAIT_BITSET in do_futex

Browse Source 
Upstream libc has recently changed to start using
FUTEX_WAIT_BITSET instead of FUTEX_WAIT and this
is causing do_futex to return -TARGET_ENOSYS.

Pass bitset in val3 to sys_futex which will be
ignored by kernel for the FUTEX_WAIT case.
