hotfix Travis: fix launch of pyTest

Clement Champetier · Clement Champetier · commit 2a17606a462d · 2015-04-28T11:34:48.000+02:00
* Install coverage tools even if Travis builds with clang ( because it's
easier to manage the command line to launch test, which uses coverage
nosetests plugin).
* Add CMake parameter to choose python version of the binding:
AVTRANSCODER_PYTHON_VERSION_OF_BINDING (Travis has updated its default python version to 3.2.3).
