Subject: [PATCH] [.travis.yml] Fix configuration to work with Ubuntu Trusty

Travis CI upgraded the linux build environment from Ubuntu Precise
to Ubuntu Trusty with Trusty becoming the default build environment
as of August 2017:

  https://docs.travis-ci.com/user/reference/overview/

A bug in the configuration of the Ubuntu Trusty distro causes all
builds except nightly to fail. The PHP include_path is set to

  include_path='.:/home/travis/.phpenv/versions/5.6.31/share/pear'

instead of

  include_path='.:/home/travis/.phpenv/versions/5.6.31/lib/php/pear'

which causes phpcs to fail because it cannot resolve import paths.

This commit adds a hotfix to .travis.yml that circumvents the
issue by overwriting the include_path during initialization. This
hotfix should be removed once a solution is found.

This bug is tracked via
https://github.com/travis-ci/travis-ci/issues/8487
