DSPSpy: Remove build.sh and sbuild.sh

This also removes the emu folder from the Makefile, and the Config.h file.  I'm not entirely sure what build.sh was for, but my best guess is that it was some kind of tool to run emulated DSP code at the same time as the actual DSP code and compare the results.  I don't know if it ever worked, but it certainly doesn't work now.
