Add Jenkins pipeline to run some i-g-t DRM/KMS tests on ODROID-XU3
using a kernel built from source. The file system with the i-g-t
tests is fixed and not built as part of this demo job as it takes a
long time to produce, but that can be easily done with a shell script
called from the debos recipe.
Add packages to the kernel-build Docker image required cross-compile
kernels and to parse the LAVA test results in YAML.
Update lava/result.py to check all the test cases are passing, not
just the overal LAVA job status.
