Allow installd to create the lib symlink for system_app_data_file

91a4f8d4fdab7df8474c2ffaa996c879166d8a4c created system_app_data_file,
and assigned all system_apps to use this file type. For testing purposes,
our automated testing infrastructure sideloads shared system UID apks.
Installd does not have permission to create the lib symlink, so the
installation fails.

Allow installd to create this symlink.
