Build and deploy sriov module only on supported hosts.

Building on the target host fixes a couple issues:
- In the containerized installer, the container image does not include
  the necessary kernel headers to build the module.
- The build and target host must have the same kernel version.  There
  is no guarantee of this.

The deploy uses NFD, similar to the QAT playbook.
