[PATCH] [luarocks] Add support for non-standard path

[Konstantin Belyavskiy]

When tarantool is installed outside "/usr" or "/usr/local" dir
luarocks can't find it. It could be done by either passing
LUAROCKS_PREFIX (which is set by -DCMAKE_INSTALL_PREFIX) to
TARANTOOL_DIR varible:
defaults.variables.TARANTOOL_DIR = site_config.LUAROCKS_PREFIX
Or by passing it to "external_deps_dirs".

Closes #3148
