bmp: Fix peer header info in Loc-RIB route message

"draft-evens-grow-bmp-local-rib" says the peer header for Loc-RIB
monitoring should include the following values;
- Peer Address: Zero-filled as remote peer address is not applicable.
- Peer AS: Set to the BGP instance global or default ASN value.
- Peer BGP ID: Set to the BGP instance global or RD (e.g. VRF) specific
  router-id.

This patch fixes the peer header construction to follow this
specification.
