by Oliver Smithggsn: osmo-ggsn.src.cfg: tweak log output
* Print log levels.
* Don't print categories as hex.
* Print the basename at the end of the line.
* Remove "logging level lgtp debug", there already is
"logging level lgtp info" further above, and this is a more sensible
setting. With "debug" there are way too many log messages in e.g.
TC_lots_of_concurrent_pdp_ctx.
