Using non-versioned scripts for `build_file` means every Python version is
tested (under Tox), and this is multiplied by each Python version running Tox.
For example, when the `python38` config is used to run Tox, the
Tox layer runs on Python 3.8. This then tests all of the Python versions
individually, including, for example, python27 tests.
This change fixes the `build_file` paths to point to the same-pathed build
script. For example, `kokoro/linux/python27/presubmit.cfg` now uses
`kokoro/linux/python27/build.sh`.
Some additional fixes:
* Use `python -m tox` in tests.sh instead of just `tox`. This helps non-site
installations of tox, where the `tox` script may not be on `$PATH`.
* Ensure tox (and other Python build-related packages) are available in
Python testing images. (New images have been pushed.)
* Disable `--warnings_as_errors` due to deprecated function.
* Remove apt lists per [Docker best practices][1].

We use six sub-modules that aren't available in old versions. Not specifying
this requirement in the setup will lead to much less readable runtime errors.
It's particuarlly problematic for Mac OSX users because the system comes with
an old six version 1.4.1 by default.

Also made the Travis build ensure that no warnings
are present.
These builds were previously spewing many warnings,
which was hiding warnings for important things like
accidentally using C++11-only features.

1, objcect_pair_hook is not supported in python2.6, so duplicated key check is removed in 2.6
2, total_seconds is not suppoted in python2.6, changed to compute seconds directly
Fixes the ScalarMapContainer/MessageMapContainer implementations on
Python 3.4, by dynamically allocating their PyTypeObjects using
PyType_FromSpecWithBases, instead of statically allocating them. This is
necessary because Python 3.4+ disallows statically allocating a class
with a dynamically allocated parent.
