travis: Update .travis.yml

For scenario_test, Python build environment is more suitable rather than
Go build environment, because scenario_test is written in Python and the
building source codes will be done on Docker containers.

This patch fixes scenario_test to use Python build environment and
reduces "sudo" executions in order to use interpreter of virtualenv.

Note: On Travis-Ci, the Python interpreter of sudoer is older version,
and when install packages with "sudo pip", InsecurePlatformWarning will
be displayed. So it is better to use the newer interpreter of virtualenv.
