[libvirt] [PATCH sandbox 1/1] Delete virt-sandbox-image tool now in separate repo

The virt-sandbox-image tool and its supporting code has been split into a separate libvirt-sandbox-image GIT repository. This allows its build system and distribution to work in the normal python way, and have a release lifecycle independent of the main libvirt-sandbox package. https://libvirt.org/git/?p=libvirt-sandbox-image.git;a=summary Signed-off-by: Daniel P.
