[Tarantool-patches] [PATCH v2 luajit 26/26] test: enable <catch_cpp.lua> LuaJIT test

[Sergey Kaplun via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

This patch moves the <catch_cpp.lua> test from the <sysdep> to <lang>
directory, includes it in <index>, and names subtests.

Resolves of tarantool/tarantool#7834
Part of tarantool/tarantool#9398
