Fix Mac path to resources and grass and sqlanywhere provider frameworks for tests

- Any test needing access to QGIS_DATA_SUBDIR (srs.db, svg, etc.) was looking for Resources in the bundled app instead
- This included failure for any call to qgscoordinatereferencesystem.cpp using srs.db and when locating svg icons
- Does not fix QGIS_DATA_SUBDIR in Python tests
- Subtests that were failing, as above, within a given test are still not triggering a fail for the test
- Symlink to grass and sqlanywhere frameworks created just for testing
