batctl: Provide different variants

The batctl binary is currently optional for batman-adv installations. But
new configuration settings will only be exposed via generic netlink. The
batctl tool will therefore be required to modify them.

To also fit batctl in some of the smaller devices, a new variant
batctl-tiny is build which only provides the settings subcommands. The
batctl-default variant is equal to the old batctl package and batctl-full
also provides the commands which were disabled until now.
