Add Drone pipeline to test packaging (grafana#6482)

* Add Drone pipeline to test packaging
Currently, the packaging process only happens on tags, which could lead to surprises
Especially considering I'm working on deb and RPM packaging (lots more steps than now)

I also moved the publishing from Circle to Drone because:
1. I'll need some new secrets from Vault
2. It should be faster

* Fix make target

* Remove `-parallel` arg for `gox`
