[Tarantool-patches] [PATCH v2 luajit 18/26] test: enable <ffi_parse_array.lua> in LuaJIT-tests

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

This patch changes `dofile()` (which uses an unreliable relative file
path and mutates `_G` with global functions to be defined) to the
corresponding `require()` of the helper functions. It adds groups with
the names of subtests and enables the test in <index>.
