Updating helm build process to not require networking

The spec files for openstack-helm-infra and openstack-helm
have been updated to not require networking, and therefore
can be built the same as other std targets rather than as
a container target.

helm init --client-only was using networking and DNS lookup.
This commit sets up helm without running that command.
