remove the suffix -arch from generated images

[sylvain-sonnen]

Hi guys,

when I generate my image with apko build, the resulting image is always owner/repo:tag-amd64. The architecture is added by apko, even if my command was:

apko build --debug --sbom-path ./sbom/ --repository-append "@local $(pwd)/packages" --keyring-append=melange.rsa.pub --arch host  apko.yaml owner/repo:1 project.tar

I expect the result to be owner/repo:1.
Is there a way do tell apko to (not) do that?

Cheers.
