bgpd: When using dev build add pointer information to %pBD

Browse source 
When building FRR with `--enable-dev-build`.  Add a bit of
code to include the pointer value as part of the output.
Helps with tracking down issues and let's us see more data
when using the dev build option.

New output:

2024/03/08 19:48:56 BGP: [V0J1J-W5RHA] 11.0.20.1/32(0x5759ddf8d7c0) for 11.0.20.1/32
