Move back the contents of the src/ folder to the root of the ropository

[icot]

• Having this folder structure causes coveralls to fail and not be able to show the source code on the coverage view
• The main problem is the Makefile generated will conflict with the one required by the Koji builds. This should not be a real issue provided that:
  • Only the main (Koji) Makefile is supposed to be tracked in Git
  • The tarball to be used during RPM is tracked by Git
  • The sources target in the Makefile is just a dummy target
