isisd: Add SRv6 locator chunks to SRv6 config

Add a list of SRv6 locator chunks allocated to a specific IS-IS area.
The list is initialized when the IS-IS area is created and freed when
the IS-IS area is destroyed. Subsequent commits will introduce the
possibility to allocate and release locator chunks.
