infra: add to luarocks support for top-level parallel make

The host-luarock dependency is not always satisfied for the extract
phase because the %-extract target is not anymore in the dependency
chain.
To be sure that the dependency is satisfied add the dependency to the
stamp file $(%_TARGET_EXTRACT) instead of the %-extract target.
