Tests: Allow shared folders in findUnusedObjects

Depending on the directory layout chosen for arranging
the squish tests the findUnusedObjects script might not
work as expected.
This patch enhances the script by adding another option
that lets you specify locations of shared folders
beside the default assumed (beside/below the location of
the objects.map)
