journald: fix flushing

Commit 74055aa762 'journalctl: add new --flush command and make use of
it in systemd-journal-flush.service' broke flushing because journald
checks for the /run/systemd/journal/flushed file before opening the
permanent journal. When the creation of this file was postponed,
flushing stoppage ensued.
