luarocks-packages.csv: changed repo by rockspec uri

This is a breaking change that converts the 'src' csv column (a git URI) to a 'rockspec'
fullpath uri.
before this, luarocks-nix would clone the repo and look for rockspecs
with a brittle algorithm. This removes the ambiguity on which rockspec
to package while allowing to remove a bunch of brittle code from
luarocks-nix.
