app-emulation/spice: Maintenance, drop obsolete USE=client (bug #566086)

- The client spicec has been removed from app-emulation/spice in favor of
  app-emulation/virt-viewer. Thus, remove the now obsolete keyword and
  associated dependencies.

- Remove (already commented out) USE="static" left-overs. This ebuild does
  not contain any executable any more for which "static" might have made
  sense.

Revision bump and commit straigt to stable as this is purely a cosmetic change.
