[Tarantool-patches] [PATCH] luajit - avoid hardcode of paths to luajit test

[Timur Safin]

We try to avoid hardcode of paths to LuaJIT tests, which
live in the 3rd party repository and might get updated
without our notice.

- to simplify cmake code we introduce symlink inside of `test`
  directory which is now pointing to `third_party/luajit/test`
  subdirectory
- and we use `file(GLOB...)` statement now to propagate list
  of all available test directories we found inside of luajit
  submodule.

Closes #5425
