Provide support for multi-arch SRIOV images

[manuelbuil]

Is your feature request related to a problem? Please describe.

SRIOV images now support arm64 but drone was not updated to push multi-arch images. As a consequence, the sriov image will use amd64 or arm64 depending on which image is pushed the last.

Example: https://github.com/rancher/image-build-sriov-operator and https://hub.docker.com/r/rancher/hardened-sriov-network-operator/tags

This is happening in all sriov images:

• https://github.com/rancher/image-build-sriov-network-resources-injector
• https://github.com/rancher/image-build-sriov-network-device-plugin
• https://github.com/rancher/image-build-sriov-operator
• https://github.com/rancher/image-build-ib-sriov-cni
• https://github.com/rancher/image-build-sriov-cni

Describe the solution you'd like

I would like all sriov images to be multi-arch (amd64 and arm64). For example like multus: https://hub.docker.com/r/rancher/hardened-multus-cni/tags

Describe alternatives you've considered

Additional context

The update of those images will be done as part of #4654

Unable to test arm64 SRIOV image support as we do not have the necessary hardware. Will cover amd64 as part validating #4654
