hide plugins in translate.wordpress.org if they load their own translations.

Hello,

In the plugin repository, some plugins are loading their own .po and .mo file.
Because these plugins are listed in translate.wordpress.org, volunteers spend time to translate, and their work are never used...
It would be better they spend time to contribute on plugins which are using the translate.wp.org translations.

I think we should think on a way to hide these plugins from translate.wordpress.org.

Example of plugin bypassing "our" translations:
​https://plugins.trac.wordpress.org/browser/wpboutik/trunk/wpboutik.php#L108
​https://plugins.trac.wordpress.org/browser/secupress/trunk/secupress.php#L447

That these plugins call load_plugin_textdomain() manually doesn't mean anything, because WordPress is first looking for translations in wp-content/languages anyway, which is where the translations from translate.wordpress.org are downloaded. So "their work are never used" is simply incorrect.
