ci: Add support for Jetson TK1.

This is a farm of 5 (6, but one fails) TK1 boards for nouveau testing,
hosted and maintained by me.  Currently it runs GLES dEQP.

I've been using ./.gitlab-ci/bin/ci_run_n_monitor.py --stress --target
gk20a to test it and am pretty confident of the skips/flakes list.  Last
night it ran 318 jobs without fail, and prior to that there were two sets
of runs in the 100-200 range where only the one failing runner failed any
jobs.
