Make CBFS output more consistent

- Prefix all CBFS output messages with CBFS:
    - Add an option DEBUG_CBFS that is off by default. Without DEBUG_CBFS
      enabled, the code will no longer print all the files it walks for
      every file lookup.
    - Add DEBUG() macro next to LOG() and ERROR() to specify which messages
      should only be visible with DEBUG_CBFS printed.
    - Actually print a message when the file we're looking for was found. :)
