Remove a few make sites

[grappler]

There are many make sites at the moment. I would like to suggest that we remove a few of them as I don't think they are needed and this would make the list of "My sites" in the admin bar shorter.

A few sites we could remove easily are:

• http://make.wordpressorg.dev/camptixtest/
• http://make.wordpressorg.dev/archive/
• http://make.wordpressorg.dev/pluginrepo/
• http://make.wordpressorg.dev/suggestions/
• http://make.wordpressorg.dev/test/
