swc-installation-test-2.py: Prefer pip to easy_install

For virtual-pypi-installer.  easy_install is part of Setuptools [1],
which was dead for several years.  The Distribute fork took over, but
has since been merged back into a revitalized Setuptools (since
Setuptools v0.7 [2], tagged on 2013-06-02 [3]).  Pip >= v1.4 actually
requires a modern Setuptools, not Distribute [4].  Pip also improves
on easy_install [5], which does not currently support uninstalling
packages [6].
