pkg/asset/cluster: Only unpack the Terraform we need

Don't unpack modules which are not needed for the target platform.
And shuffle our modules around to collect the per-package stuff
together.  Now that we have a single Terraform step and all the shared
asset generation is in Go, we can dispense with the modules/
distinction.
