utmctl: add version command

For the scripting backend, we have to use a hack. The existing property
`version` cannot be accessed through App Sandbox because the inherited
suite does not define an access-group. We create a new property that is
accessible by the com.utmapp.UTM.vm-access access group.

Resolves #7350
