emacs: remove obsolete Reddit frontends

Reddit changed the terms of its APIs which essentially killed all
third-party clients. As a result Libreddit cannot be used anymore. [0]

This is very unfortunate since Libreddit was working quite well in EWW.
Now I'm using old.reddit.com which is still better than the regular
Reddit website but still pretty bad in comparison to Libreddit.
