[Tarantool-patches] [PATCH luajit 10/25] test: enable <ffi_gcstep_recursive.lua>

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

This patch declares functions as local to avoid pollution of the global
environment. It separates the body of the test in the `do` `while` block
and includes the test in <index>.

Part of tarantool/tarantool#9398
