Change TARGET_RECOVERY_UI_LIB to use fully qualified names in gs101

Since the TARGET_RECOVERY_UI_LIB for each device is not exactly the
same, and most of the modules in it contain `soong_namespace{}` to
avoid conflicts between different devices, after converting
`librecovery_ui_ext` from Android.mk to Android.bp, it needs to be
changed to a `fully qualified name` in order to correctly use the
corresponding module.
