Bug 930808 - Upgrade to psutil 2.1.3; r=glandium

psutil 2.1.3 is replacing psutil 1.0.1. There are numerous bug fixes and
feature enhancements in psutil worth obtaining.

Source code was obtained from
https://pypi.python.org/packages/source/p/psutil/psutil-2.1.3.tar.gz and
uncompressed into python/psutil without modification except for the
removal of the egg-info directory and the .travis.yml file.
