[PATCH 2.6] compat_sys_[gs]etsockopt need to check for level

The 32bit emulation functions for setsockopt/getsockopt try
to catch a few special cases by looking at the option name,
without checking for the option level. This breaks IPV6_V6ONLY
and probably a few others.

The bug was found by Marcus Meissner.

I hope I got the level for IPT_SO_SET_REPLACE right (I think it's SOL_IP).
I would appreciate if someone could double-check.

Cheers,
Olaf
