expectation update patch for any pipeline

There is a subcommand in ci-uprev called "collate" that is part of the split to have ci-collate.

Both provide a way to see which tests failed and they are at one simple step to provide a expectation changes patch.

When ci-uprev, requiring too much in environment variables, can return:

export TARGET_PROJECT_PATH="mesa/mesa"; \
export export FORK_PROJECT_PATH="gfx-ci-bot/mesa"; \
export DEP_PROJECT_PATH="mesa/piglit"; \
python ci-uprev.py collate 819067

Only collate results from pipeline 819067 in gfx-ci-bot/mesa.

Downloaded artifacts for 'zink-lvp' from 'results/failures.csv' at https://gitlab.freedesktop.org/gfx-ci-bot/mesa/-/jobs/37244543
Failures:
{"('zink-lvp', 'layered-backends')": {'glx@extension string sanity': ['UnexpectedPass']}}

ci-collate provides almost the same information but knowing the jon ids:

ci-collate --namespace gfx-ci-bot \
           --project mesa \
           pipeline --status failed \
                    --artifact 'results/failures.csv' \
                    819067

{'zink-lvp': {37243489: 'glx@extension string sanity,UnexpectedPass\n',
              37244543: 'glx@extension string sanity,UnexpectedPass\n'}}

Users would use ci-collate, but right now it is ci-uprev who knows about expectations, so it this tool the first that can include this information.
