tools: remove qvm-ls tool and related integration in qubes.property

qvm-ls tool (as all other tools) will be accessing properties through
API, so no need (nor sense) for this tool-specific attributes in
qubes.property. The only somehow used was ls_width, and in fact it made
the output unnecessary wide.

The tool itself is already moved to core-mgmt-client repository.
