[sonic-utilities] Explicitly run unit tests in build script (sonic-ne…

…t#166)

When we were building the sonic-utilities package as a Debian package, the `python setup.py --command-packages=stdeb.commandbdist_deb` operation would automatically run the unit tests before build. Now that we've changed to building a Python wheel, the `python setup.py bdist_wheel` operation does not automatically run the unit tests.

In this patch, we explictly run the unit tests using `sudo python setup.py test` before building the wheel.
