move repo from Luarocks to LunarModules

[Tieske]

Since luacov is already under the LunarModules org, we should probably also move this one there, managed by the same team.

Wdyt @hishamhm @alerque ?

[alerque]

Makes sense to me.

[hishamhm]

Sounds good to me too.

I don't have the rights to move it, can you transfer it @hishamhm ? probably also means transferring the ownership of the rocks on luarocks.org.
