prerequisites: upgrade pip version

Some versions of pip (in particluar v1.5.4 which comes with Ubuntu 14.04) are know
to set the wrong permissions when installing packages, resulting in WA failing to
import them. To avoid this it is recommended that you update pip and setuptools
before proceeding with installation.

Following file upgrade pip version on kvm host machine before install-wa2.sh
- prerequisites.sh
