Cert: Add virtualenv setup for cert tests
* Add cert/set_up_virtualenv.sh for cert tests so that:
1) We can use common IDEs that work with virtualenv to edit GD cert
tests and libraries
2) We no longer have to use PYTHONPATH when running tests
3) Explicitly list dependencies in virtualenv setup to make the setup
more Android independent as it really just need that two ZIP files
* Fixed some import directives as gd/ should always be the import root
event when importing from the same directory
Bug: 148147248
