Introduce VSOCK link type

This address family is used in communication between virtual machines
and their hosts. Advantages include that no virtual ethernet adapter
and their respective address configuration and routing need to be
setup. Rather, with this new link type, only a single yggdrasil
interface can exist inside of the virtual machine.

It can also be used inside of containers. There, the advantage over
existing link types like unix sockets include, that no mount point
need to be shared with the host and container. This provides more
isolation.
