Use tools v5.2 (#903)

* Use [tools v5.2](https://github.com/openmaptiles/openmaptiles-tools/releases/tag/v5.2.0)
* Use `mbtiles-tools meta-generate` instead of the removed `generate-metadata` script.
* Remove `show-metadata` make target - it was just added and is not needed.

## Relevant changes
* Upgrade [osml10n PG extension](https://github.com/giggls/mapnik-german-l10n) to the faster v2.5.9 (significant performance improvements merged upstream by @nyurik)
