Rename sdcard_internal/external types to fuse and vfat respectively to make it clear that they are assigned to any fuse or vfat filesystem by default (absent a context= mount option) and do not necessarily represent the SDcard. The sdcard_type attribute is still assigned to both types and can still be used in allow rules to permit access to either the internal or external SDcard. Define type aliases for the old names to preserve compatibility on policy reload and for device-specific policies that may not yet be updated.
