Title: [WIP] Set travis to test old versions of numpy and scipy too

Modified version of @ogrisel #3022 to have more robust lars test.

This is a tentative PR (to check travis build) to improve the travis config by:

* use cleaner multiline scripts in separate files
* test old versions of numpy and scipy with python 2.6
* use the travis managed apt cache
