forkfd: introduce forkfd_wait4() that takes options
"wait4" because it looks like the wait4() BSD function, which has the
signature:
pid_t wait4(pid_t pid, int *wstatus, int options,
struct rusage *rusage);
And because ours also has 4 parameters.
Having options is important anyway. I might want to add some more later,
but we can't really support them with the fall back implementation (in
fact, we don't honor WNOHANG in the fall back implementation either).
