This commit extends most test cases in ipmr.c for IPV6MR.
Note that IP6MR does not provide rtnetlink interface for MFC,
so such tests are added to XFAIL_ADD().

The new test exercise paths, where RTNL is needed, to
catch lockdep splat:
setsockopt
MRT_INIT / MRT_DONE
MRT_ADD_VIF / MRT_DEL_VIF
MRT_ADD_MFC / MRT_DEL_MFC / MRT_ADD_MFC_PROXY / MRT_DEL_MFC_PROXY
MRT_TABLE
MRT_FLUSH
rtnetlink
RTM_NEWROUTE
RTM_DELROUTE
NETDEV_UNREGISTER
I will extend this to cover IPv6 setsockopt() later.
