Subject: [PATCH] The old g_want_determinism check in WiiSockMan missed a few
 cases.  Move to net.cpp.

Specifically, things like GETHOSTBYNAME, GETHOSTID, etc. could be done
without creating a socket, which is what the old check blocked.  Now we
check at the ioctl and ioctlv handlers.  Might be possible to get a bit
more realistic behavior in future by filtering individual ioctls, but it
probably doesn't matter.
