Travis: also test on 32-bit Linux
When Git v2.9.1 was released, it had a bug that showed only on Windows and on 32-bit systems: our assumption that `unsigned long` can hold 64-bit values turned out to be wrong. This could have been caught earlier if we had a Continuous Testing set up that includes a build and test run on 32-bit Linux. Let's do this (and take care of the Windows build later). This patch asks Travis CI to install a Docker image with 32-bit libraries and then goes on to build and test Git using this 32-bit setup.
