Commit eb25a7da639e ("Improve debuggability of OVN to OpenFlow translations.")
added support for more types of cookies (partial SB uuids) that are stored
in OpenFlow entries created by ovn-controller.

The last patch in this series implements support for parsing all these
different cookies in ovn-detrace too.

The first patch is a bug fix required as ovn-detrace was broken after
moving OVN to its own separate rundir.

The second patch fixes line parsing in ovn-detrace.

v3:
- Remove stray "%s".
- Rename pprint to print_p to avoid name clashes with the library function.
v2:
- Address Mark's comments:
  - properly handle potential collisions between cookie -> UUID mappings.
  - when looking up SB records by cookie, match on the first part of the
    UUID.
- Further refactor ovn-detrace to simplify prefixing outputs.
- Change print statements to print() calls.
