return site_config

This configuration (May 2014) was done at a stage when the current
Lua was 5.2, Lua 5.3 was sitting in my home directory. But luarocks
itself was updated in March 2015 when the current Lua was 5.3.

Is there a way to ask luarocks to reconfigure?

If not, is it safe to just edit the config file manually?
