Allow readdir(/proc/[tid]/net) to return EINVAL on a zombie task.
Despite what the man page says, linux will return EINVAL when calling
getdents() an a /proc/[tid]/net file corresponding to a zombie task. This
causes readdir() to return a null pointer AND errno=EINVAL.
See fs/proc/proc_net.c:proc_tgid_net_readdir() for where this occurs.
We have tests that recursively read /proc, and are likely to hit this when
running natively, so we must catch and handle this case.
