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. PiperOrigin-RevId: 317674168
