builder: map koji api image types to cloud ones

Map the image types used by the koji API to the image types used
by the cloud api. This should allow for a smooth transition when
the plugin is upgraded, i.e. the pungi configuration can be used
unmodified. After all the plugins are upgraded the pungi config
should be changed to use the native image types and then this
mapping could be removed again.
