scripts/runqemu-internal: Work around qemux86 PAT bugs in linux 4.4.1

Since the upgrade of qemux86 to 4.4.1 we're seeing PAT issues when
starting the X server. We need to fix the problem but the failing
sanity tests mask out other issues and we need a workaround.

Merge this for now until we can figure out the full issue. This is
better than changing the kernel defconfig or reverting to old
kernel versions.
