To support transparent (de)compression in iso9660, we need mkzftree,
which comes from zisofs_tools, biundled with cdrkit.
However, cdrkit is a cmake package, but zisofs_tools is an autotools
package, so we need a separate package just to get mkzftree, but it is
pretty lightweight.
We just need the host variant for now,so we just add that.
