  CI: Install g.download.location only if needed (#591)

- g.download.location is included in the core for v8 and is installed with all the other addons too (currently same for in both).
- g.download.location is now installed only if missing.
- Use path instead of dbase as in the core version of g.download.location (addons version supports both).
