Title: Allows tests to run against FOG_RC setting

https://github.com/fog/fog/commit/dce5e800fdebefdb64ea5ccd3418c80518d43276 introduced
changes in the test helper to use a specific test file (`tests/.fog`)
and set of credentials (`default`) for tests.

This changes this to honour the existing environment variables if set.

I use multiple configs to test against different versions of endpoints and the original change messes up that workflow and some of our CI settings.
