[Tarantool-patches] [PATCH v2 5/6] Add luacheck config

[Vladislav Shpilevoy]

Hi! Thanks for the answer!

I still think, that if a whole folder was ignored in exclude_files, then
it does not make sense to add individual files from this folder again.
Anyway we won't be able to maintain warning ignorance for these files,
because they are just invisible for luacheck.

But I will leave it to a second reviewer. Igor wanted to take a look too.
