Subject: [PATCH] Travis: decrease Windows itest parallelism

The Windows virtual machine that Travis runs the integration tests on
seems to be slower than the other machines. We try to increase the
stability of the tests by cutting the number of parallel running suites
in half. This will come at the cost of longer execution time but
hopefully with a better stability in return.
