linux-user: Add missing IPV6 sockopts 

When running ssh over IPv6 with linux-user I faced this warning:
 Unsupported setsockopt level=41 optname=67
 setsockopt IPV6_TCLASS 32: Protocol not available:

This patch adds code to the linux-user emulatation for setting and
retrieving of a few missing IPV6 options, including IPV6_TCLASS.
