Added a VOXL 2 board specific shutdown hook to run on exit

[katzfey]

Solved Problem

If the apps processor side of PX4 running on VOXL 2 exits the DSP side continues on. If PX4 is then restarted it will fail because the DSP side will still be running the old instance. This PR will send a new custom kill command to the DSP to reset it and get it back into it's ready state. This is done within a shutdown hook that's installed on px4 start up.
