This fixes the following issue where spice-vdagent would fail to start if the spice-vdagent-sock socket file already existed: spice-vdagentd: Fatal could not create the server socket /run/spice-vdagentd/spice-vdagent-sock: Error binding to address: Address already in use The requirement is also modified to depend on dbus-system, a cue taken from upstream's own systemd service file (see 'data/spice-vdagentd.service' in the sources). * gnu/services/spice.scm (spice-vdagent-activation): Delete procedure. (spice-vdagent-shepherd-service): Fix indentation. [requirement]: Replace udev by dbus-system. [start]: Ensure the spice-vdagentd run-time directory exists and that the spice-vdagent-sock socket file does *not* exist before forking the daemon.
