[Libosinfo] [osinfo-db-tools PATCH 4/7] tests: Add osinfo-db-path tests

[Fabiano Fidêncio]

Add a set of functional tests to ensure osinfo-db-path works as
expected. The covered scenarios are:
- osinfo-db-path --system
- osinfo-db-path --local
- osinfo-db-oath --user
- osinfo-db-path --dir
- osinfo-db-path --root ROOT --system
