[Tarantool-patches] [PATCH 18/19] Add luacheck supression for luajit test

[Igor Munkin]

Sergey,

Here we go again... I wonder how exactly you tested LuaJIT related patch
if you ended up suppressing the same warning both inline and within
.luacheckrc. Consider the following:
| $ git diff | cat

So what does this suppression fix? Actually nothing. Please drop this
suppression from .luacheckrc (and thereby the patch itself).

By the way, I see another problem:
- Wait, it's all just luacheck failing on luajit tests?
| $ git co HEAD^
| $ git log --oneline -1 | cat
| c9653cbec Add luacheck supression for luajit test
| $ make luacheck || echo "Always has been"
| <snipped>
| Total: 95 warnings / 0 errors in 492 files
| make[3]: *** [CMakeFiles/luacheck.dir/build.make:58: luacheck] Error 1
| make[2]: *** [CMakeFiles/Makefile2:430: CMakeFiles/luacheck.dir/all] Error 2
| make[1]: *** [CMakeFiles/Makefile2:437: CMakeFiles/luacheck.dir/rule] Error 2
| make: *** [Makefile:316: luacheck] Error 2
| Always has been

I guess the agreement to make the series passing <luacheck> after
*every* patch still stands (like you made for src/ and extra/
directories). I doubt we should violate this rule for test/.
