Use versioned files only. (#734)

Let's take the opportunity of a new major version to make an important cleanup: getting rid of the error-prone unversioned configuration files. This drops support for:

* Unversioned config.lua -> use config-5.x.lua
* Unversioned luarocks/site_config.lua -> it always generates luarocks/core/site_config_5_x.lua
* Unversioned lib/luarocks/rocks -> it always uses lib/luarocks/rocks-5.x
