runvm-osbuild: rework podman images hack

Narrowing in further on why this is required leads to an
issue with permissions when supermin is creating the filesystem
for the supermin VM.

Opened containers/common#2507 upstream
to address this, but for now let's fixup the permissions in our
image build.
