safe_z_home: Fix final z hop to use relative z coordinates (#5879)
After a G28 z-axis homing, there is a final z hop.
It was hoping to height z_hop as an absolute z height rather than relative.
If the z-axis home leaves the head at a z height higher than z_hop,
e.g. because you were using a probe to do z homing,
this meant that it was z hopping in the negative z direction, which
could result in crashing the toolhead.
