[Tarantool-patches] [PATCH v2 luajit 10/26] test: enable <ffi_enum.lua> in LuaJIT-tests

[Sergey Kaplun]

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()` call and renames the C library in the
`require()` call. Also, it names all subtests and includes the test in
<index>.
