In order to help our efforts finalizing the initial release, provide a
little bit of info to the user about the detected config and the
firmware path belonging to the installation.
TODO: This can be improved in various ways:
- Clear sony.modemswitcher.modem_name_*, and wait for it to change.
This variable contains the path so that we do not need to read it from
a file, including the default path (when the config is not found).
- Extend the notification (or start a Dialog/Activity onclick) to
display more diagnostic info.
