    build: Don’t link backend libraries with libfolks-internal.la helper
    
    Because libfolks-internal.la is a libtool helper library, and is never
    actually installed, it gets statically linked into each backend. This
    means that the GObject types in it (such as FolksSmallSet) get
    duplicated between libfolks.so and each backend. This causes GObject
    errors when the backends are loaded and attempt to re-register types
    which already exist.
    
    This is a partial revert of commits:
