Travis-CI: fix configuration after September's update

The latest update to Travis-CI build environment splitted sugilite
environment into amethyst and garnet and deprecated sugilite. As garnet
provides tools for languages C and Python, and as it is automatically
selected according to
https://travis-ci.org/fishilico/selinux/jobs/278927391 , remove "group:
sugilite" from Travis-CI configuration file.

This update introduced two issues:

- Ruby 2.1 is no longer provided. As it has reached End Of Life
  according to https://www.ruby-lang.org/en/downloads/, remove it from
  the tested versions

- Python 3.3, 3.4 and 3.5 are no longer installed by default. When
  Travis-CI builds Python projects using these versions, it
  automatically download and extract an archive from
  https://s3.amazonaws.com/travis-python-archives/binaries/ubuntu/14.04/x86_64/.
  Implement this process in .travis.yml directly (because Travis-CI does
  not support multi-language projects which use several versions of C
  compilers and Python and Ruby interpreters).

Last but not least, it is now possible to build with PyPy3. Enable this
interpreter in the build environment matrix.

More information about the Travis-CI update is available at
https://docs.travis-ci.com/user/build-environment-updates/2017-09-06/
