The new commit message is the following:

| test: enable <ffi_const.lua> in LuaJIT-tests
|
| This patch changes the `dofile()` (which uses an unreliable relative
| file path and mutates `_G` with global functions to be defined) to the
| corresponding `require()`. Also, it splits the test case into several
| and includes the test in <index>.

| Part of tarantool/tarantool#9398
