modules: Make requiresTests a list of paths.

Unfortunately, we went into trouble and the Hydra machine not only
consumed lots of ram during evaluation but it also triggered a bunch of
evaluation errors because the available tests were strictly evaluated.

Using attribute paths consisting of plain strings doesn't have the same
problem, even though they look a bit uglier.
