futex: wake one waiter if futex_wake is called with a non-positive value
This change is needed to be compatible with the Linux kernel.
There is no glibc wrapper for the futex system call, so it is easy to
make a mistake and call syscall(__NR_futex, FUTEX_WAKE, addr) without
the fourth argument. This works on Linux, because it wakes one waiter
even if val is nonpositive.
