Daniel Edgecumbe a95686bb5d journal: Make the output of --update-catalog deterministic
The use of an unordered hashmap means that the output of
'journalctl --update-catalog' differs between runs despite there being no
changes in the input files.

By changing all instances of Hashmap to OrderedHashmap we fix this, and now
the catalog is reproducible.
