services: spice-vdagent: Clear the socket file prior to starting.
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.
