prepare-host: use qemu-user-binfmt on Ubuntu resolute

Ubuntu 26.04 (resolute) split qemu-user-static into qemu-user-binfmt
and qemu-user-binfmt-hwe, leaving qemu-user-static as a virtual
package with two providers. apt won't auto-pick a provider, so the
generated Dockerfile (and any direct ./compile.sh requirements run on
a resolute host) fails with:

    E: Package 'qemu-user-static' has no installation candidate

Match the existing python2 pattern (release-conditional host deps)
and pick the concrete non-HWE package on resolute. Older releases
keep qemu-user-static.
