introduce spec file and related build scripts

The repository now contains a Vagrantfile for running the testing script
against an RPM package created locally using `make rpm`. To run this
test use `make vagrant-test`. setup.py was also modified to adhere to
packaging guidelines and not to install system-level executables.
The lincense is now included in the Python package using the MANIFEST.in
file.
