bltouch: Verify probe always deploys during a homing operation

Verify that there is always some movement during a probing operation.
This is normally done by the homing.py code (via its verify_movement
check), but that check may not be enabled when z_virtual_endstop is
used.  So, always enable the check in the bltouch.py code.
