Initialize WaylandSessionPrivate.vt to -1

This matters when starting a Wayland session on a non-seat0 seat:
  * It eliminates an erroneous attempt to switch to VT 0.
  * The XDG_VTNR environment variable is no longer set.

Also add a multiseat test.

A similar change for XServerLocalPrivate is not needed because its vt field is
already initialized to -1.
