virtualenv-tools has a bug which gets triggered in gates: it can't change the shebang of a virtualenv python bin/ files if they were generated with a virtualenv script whose shebang ends with python2 instead of python. Because we can't modify virtualenv-tools, we use shell scripts instead. Change-Id: Iad3a44f35c57d92dcbbfde4acbd86a3a4eb1879d Partial-Bug: #1741634
