New test-suite for LuaRocks (#581)

First version of new test-suite, using Busted framework based on Google Summer of Code project:
https://summerofcode.withgoogle.com/projects/#5695811874717696

* Rewritten from Bash to Lua
* Tests now check if they did what they were supposed to, beyond only checking success or failure of the `luarocks` command
* Support for black-box (launching `luarocks` as an external command) and white-box (testing functions in modules directly) testing
