isisd: fix multiple values display in show isis database detail json

Browse Source 
Multiple occurrences of the same (sub-)TLVs are mixed into a single JSON
object. Last values replaces the previous.

Display all the occurrences in an array for the following (sub-)TLVs:
- is-reach
- ip-reach
- ext-reach
- ext-ip-reach
- ipv6-reach
- MT
- prefix-SID
