android: Show error if invalid keys file is selected 

There aren't MIME types specific enough for filtering out files that aren't amiibo or production keys. So here we just check for the extensions "bin" or "keys" where appropriate and stop the process if incorrect. Previously you could select any document and it could cause the app to hang.
