kernel-netlink: Remove unimplemented XFRM_OFFLOAD_IPV6 flag

The XFRM_OFFLOAD_IPV6 flag was never implemented in the kernel and there
are no plans to do so.

Kernel patch: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=7c76ecd9c99b6e9a771d813ab1aa7fa428b3ade1

Closes strongswan/strongswan#916
