Mantis: play power off tune

Browse Source 
To play a power off tune, I needed to convert the file to C++, so that I
could use the uORB::Publication.

The current implementation starts playing the power off sound but then
stops it as soon as the button is released.

The problem is mostly that we only get an interrupt when the button is
pressed or released but we don't seem to be able to poll it, at least
not in the current state.
