ci/bare-metal: Consolidate needs declarations in .baremetal-test-*.

We had it set up for arm64 asan already, do it for everyone else too. In cleaning up the duplication, this fixes a pasteo in rpi3 which had the "artifacts: false" on the wrong job, causing it to do a slow download of the mesa build from gitlab.

Should save about 20 seconds on rpi3 jobs.
