Tuomas Tynkkynen d78d168096 travis-nox-review-pr: Try to detect if the build ran out of memory
Travis builds sometimes fail because Travis doesn't have much memory.
When it happens, the failure reason is often hard to see in the logs and
is confusing (especially for new contributors).

Try to detect OOM errors in dmesg and give a warning when it happens.
