iptables: xtables-eb: user-defined chains default policy is always RETURN

The RETURN default policy is mandatory in user-defined chains.
Builtin chains must have one of ACCEPT or DROP.

So, with this patch, ebtables-compat ends with:

Command:                             Result:

-L                                   Always RETURN for user-defined chains
-P builtin RETURN                    Policy RETURN only allowed for user defined chains
-P builtin ACCEPT|DROP               ok
-P userdefined RETURN|ACCEPT|DROP    Policy XYZ not allowed for user defined chains
-N userdefined                       ok
-N userdefined -P RETURN|ACCEPT|DROP Policy XYZ not allowed for user defined chains
