[CRIU] [PATCH 3/3] s390: Enable travis

[Michael Holzheu]

We have to use "debian.jessie" instead of "ubuntu.xenial" because
qemu-s390x-static can only run z900 instructions and Ubuntu is
built with a more recent architecture level set.

We first enable only gcc because there are still some issues with clang.
