safe_z_home: Fix final z hop to use relative z coordinates (#5879)

Browse source 
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.

## Changes
20221114: Previously, with safe_z_home, it was possible that the
z_hop after the g28 homing would go in the negative z direction.
Now, a z_hop is performed after g28 only if it results in a positive
hop, mirroring the behavior of the z_hop the occurs before
the g28 homing.
20220616: It was previously possible to flash an rp2040 in bootloader
mode by running `make flash FLASH_DEVICE=first`. The equivalent
command is now `make flash FLASH_DEVICE=2e8a:0003`.
