[PATCH 2/7] test: provide testfs via fixture

[Jonas Rebmann <jre@pengutronix.de>]

Move the logic of providing testfs out of the tests and into a fixture.
Pytest-modules that prepare testing data in their own fixtures should
build on top of this.

Tests using the fixture will be skipped if the feature is unavailable;
remove that check from existing tests.
