Tests: fix memory leak of GHOST system paths

Dispose of GHOST system paths when tearing down `BlendfileLoadingBaseTest`
and some other test cases. This prevents a memory leak.

A better solution would be to rework Blender's initialisation & teardown
structure, but that's outside the scope of this fix.

No functional changes to Blender.
