    tests: childhurd: Prefer “-cpu max” over “-cpu host”.
    
    “-cpu host” can sometimes, for unclear reasons, lead to this error from
    QEMU 8.1.1:
    
      qemu-system-x86_64: CPU model 'host' requires KVM or HVF
    
    This commit fixes it.

    * gnu/tests/virtualization.scm (run-childhurd-test)[test]: Prefer
    “-cpu max” over “-cpu host”.
