kern_log_whisper_hang-chain_glk

In GLK, with IGT-Version: 1.20-g6d27aca (x86_64) (Linux:
4.15.0-rc4-drm-tip-ww52-commit-05590c3+ x86_64), the tests:

igt at gem_exec_whisper@contexts-forked
igt at gem_exec_whisper@fds-forked
igt at gem_exec_whisper@fds-priority

Are all success, while the test:

igt at gem_exec_whisper@hang-chain-forked 

Do _not_ fail, but it takes around 9 hours to complete. I believe is the same
case for the others platforms, but I haven't tested yet. And again, we have
another test that takes too much time to finish to add to the list.
