Revert most of ce42e793100b460f597e4c85ec0da12e274f9394
to restore ABI compatibility for pre-10.x binaries.
It restores _umtx_lock() and _umtx_unlock() syscalls, and UMTX_OP_LOCK/
UMTX_OP_UNLOCK umtx_op(2) operations. UMUTEX_ERROR_CHECK flag is left
out for now, I do not think it makes a difference.
