fix(dracut-logger): do not export maxloglvl and syslogfacility

Commit 46265a9d3e0a ("dracut-logger: make $maxloglvl public") exports
the `maxloglvl` variable, but this is not needed. Exporting variables is
only needed when subprocesses need to access those variables.

`maxloglvl` is only used in `dracut-logger.sh` and `dracut.sh`.
`dracut.sh` sources `dracut-logger.sh`. So exporting `maxloglvl` is not
needed. `syslogfacility` is only used in `dracut-logger.sh`.

So do not export `maxloglvl` and `syslogfacility`.
