Enable to build kata-agent with PULL_TYPE feature.
We build kata-agent with guest-pull feature by default, with PULL_TYPE set to default.
This doesn't affect how kata shares images by virtio-fs. The snapshotter controls the image pulling in the guest.
Only the nydus snapshotter with proxy mode can activate this feature.

We're moving away from alpine and using ubuntu in order to be able to
build the agent for all the architectures we need.

Let's add the needed functions to start building the kata-agent, with or
without the OPA support.
For now this build is not used as part of the rootfs build, but later on
this will (not as part of this series, though).
