babeld: Add interval and router-id field checking

[zmw12306]

According to RFC 8966: https://www.rfc-editor.org/rfc/rfc8966.html#name-details-of-specific-tlvs

Add checking for interval and router-id:
The interval MUST NOT be 0 in Acknowledgment Request, IHU, Update

The Router-Id MUST NOT consist of all zeroes or all ones.

[zmw12306]

The router-id check should also be done in Seqno Request
