Add an $APP_DATA_DIR predefiend thingie in bootstrap ("rc") files for Android

It expands to what lo_get_app_data_dir() returns, i.e. the activity's
getApplicationInfo().dataDir.

Use it in the LibreOffice4Android app's rc files instead of a
hardcoded (possibly device- and/or OS version dependent) path.
