bgpd: Fixes to error message printed for failed peerings

There was a silly bug introduced when the command to show failed sessions
was added. A missing "," caused the wrong error message to be printed.
Debugging this led down a path that:
   - Led to discovering one more error message that needed to be added
   - Providing the error code along with the string in the JSON output
     to allow programs to key off numbers rather than strings.
   - Fixing the missing ","
   - Changing the error message to "Waiting for Peer IPv6 LLA" to
     make it clear that we're waiting for the link local addr.
