Symlinking $CARGO_HOME to /usr/local/bin made rustup uninstaller delete
the entire folder, causing mysterious build errors, so let's do the
traditional .cargo/env sourcing to make rustup available to the rest of
the build scripts.
Also make sure that required scripts run the shell's rcfile to be able
to setup the PATH correctly.

I found the C++ runner hard to develop on, and we had stability issues and
outstanding feature needs that made me want something I felt good about
hacking on. Thus, Rewrite It In Rust of the deqp runner.
The new runner includes:
- Skip lists don't reshuffle the test list.
- Known-flake handling without resorting to skip lists (fixing our main CI
reliability issue on a3xx right now).
- Per-thread Vulkan shader caches should speed up VK CI runtime.
- Tracking of crashes separate from fails (so we can see progress on that
front).
- Logging of deqp stderr spam (particularly assertion failures!) in the CI
log.
- Integrated QPA filtering so we don't have bash perf issues for it.
- Logging of what caselist to go look at for a given error report (in red,
so it's easier to find in your CI log).
- The code is 1/3 unit tests, and easy to extend for more coverage.
- Non-LAVA CI runs create a failures.csv in artifacts that you can check
in as your deqp-*-fails.txt file.
- Test runtime is included in results.csv so you can debug how to speed up
your CI job.
- Pretty summary at the end of the run of slow/flaky/failed tests.
Since this is a new runner with a different RNG, the test groups are
shuffled one more time. This seems to result in some panfrost T720
stability issues (See its new deqp-panfrost-t720-flakes.txt), and one new
flake in freedreno a630.
