https://github.com/tarantool/tarantool/issues/4629
https://github.com/tarantool/luarocks/tree/lvasiliev/gh-4629-add-chdir-to-make
See corresponding patch for tarantoolctl
(https://github.com/tarantool/tarantool/tree/lvasiliev/gh-4629-forward-flags)

Motivation:
Imperfect integretion of the Luarocks to tarantoolctl
(enable some commands)

Was done:
whitelist of tarantoolctl don't used for luarocks flags
Option chdir has been moved from tarantoolctl to luarocks
