[virt-tools-list] [PATCH virt-viewer] vnc-display: Disable default grab sequence

[Pavel Grunt]

It should be enabled only if the "release-cursor" sequence was not
specified (by using "--hotkeys=release-cursor=sequence"), otherwise
both sequences would release the cursor.

The solution is taken from the spice-display code.
