Stop using subprocess for testr init in tempest init

This commit switches the call to testr init from using subprocess to
testr's python run_argv interface. (which is essentially just calling
it via subprocess) The issue with using subprocess directly is that it
assumes testr is in the PATH you're running from. But, in the case of
using a venv this isn't always the case.
