testing/spice-vdagent: fix copy / paste functionality

This patch adds an init script for copy & paste functionality between
the guest & host. Run 'rc-service spice-vdagentd info' for details on
the settings for libvirt.

By default this runs with a single session possible. For multiple sessions
remove '-X' to disable consolekit from the init script & install slim or lxdm.

Tested on 32 & 64 bit KVM - but should also work on XEN / LXC run by libvirt.
