tests: enable doctests in the sources

Unfortunately the "standard" way to access the names in the
defined module does not work. I find it nicer to explicitly import,
e.g. from systemd import journal, because then the examples
correspond more closely to what a user would use. The only
exception is made for JournalHandler, because journal.JournalHandler
is a tad to long.
