isisd: Add format func for Sub-Sub-TLVs in general

Add a function to return information about all the Sub-Sub-TLVs passed
as an argument.

At this time, this function does nothing because no Sub-Sub-TLVs have
been defined yet. This function will be extended in
future commits to return information about specific Sub-Sub-TLVs,
as they become supported.
