Remove ancient code to import keys from ancient plugins

There were a couple specific DRM removal plugins before the DeDRM plugin
was created. These are obsolete since a long time, there's no need to
still have the code to import their config.

If people are still using these ancient plugins, they'll have to update
to an older version of DeDRM first, and then update to the current one.
