Paul Holzinger 042c1ffa0b pkg/machine/e2e: use testimage
The alpine_nginx image is a static amd64 only image, just yesterday our
CI broke because the rosetta emulation stopped working. All these tests
should have no need to test emulation and should just run on native arch
here. This should also make them faster.

If we want to test emulation work it should be done in the
podman-machine-os tests instead.
