feat(go4k&sointu): Export .h C header files from the songs using go, also automatically during build for the tests.

Browse Source 
The header files are automatically generated during build. No need to #define anything; everything is fixed by the .asm file. This adds go as a dependency to run the unit tests, but this is probably not a bad thing, as go is probably needed anyway if one wants to actually start developing Sointu.
