Michael Vogt 6bfd3424e8 journalctl: add follow mode to the varlink method
This commit implements `journalctl -f` like behavior for the
varlink API of journalctl. It is used via:
```
$ varlinkctl call -E \
    /run/systemd/io.systemd.JournalAccess \
    io.systemd.JournalAccess.GetEntries '{"follow": true, "limit": 10}'
```
This gives the last 10 message and then it keeps the connection
open and output each new log line that matches the set filters.

The code is modeled after `journalctl -f`. It seems there is little
to extract into shared code here so I left it for now.
