linux: Support IPPROTO_RAW socket option translation

Browse Source 
Handle Linux IPPROTO_RAW socket options in the Linuxulator for both
getsockopt(2) and setsockopt(2). Detect the socket family and remap
the level to IPPROTO_IPV6 for AF_INET6, reusing the existing option
translators.

This fixes IPV6_CHECKSUM for IPv6 raw sockets, which Linux programs
set at level IPPROTO_RAW rather than IPPROTO_IPV6.
