lists: move some of the IPv6 protocols to base-min and drop the rest

There is no reason to have IPv6 separate from other network protocols.
They should be in same place and installed together.

Preserved protocols:
* ds-lite: it is widely deployed over the world so it is probably a must
  have.
* 6in4: common tunneling protocol used to get IPv6 to networks without
  it. As a way to push IPv6 we should include it.
* 6rd: a replacement for 6to4 in some way. It is a way to provide IPv6
  in IPv4 only network on ISP's network. There seems to be minority of
  ISPs actually using it.

Removed protocols:
* 6to4: marked as deprecated.
