Add missing -l and -L options kvm-install-vm remove

Add the -l and -L options to the kvm-install-vm remove command to
specify the paths to the images and guest files. Those options are
required if they were given in the previous kvm-install-vm create
command, otherwise the remove will fail to remove the items created with
the custom paths.
