probe: Infer position_endstop when using probe:z_virtual_offset

Browse Source 
Don't require (or permit) the user to specify a stepper_z
position_endstop when using the probe:z_virtual_offset mechanism.  In
that case the position_endstop should always equal the probe's
z_offset - so no need to have the user specify it.
