Implement suite-based dkms enablement list, driven / configured from matrix.

PR#94 is merged to enable the camx and iris dkms bundling for debian based suites, but as a temporary workaround. The proper solution is to allow for suite-based dkms enablement list, driven / configured from matrix.

The override to unwind is the SUITE_FAMILY == ubuntu block in build-kernel-deb.yml that replaces the list with kgsl, plus the needs: resolve on the prepare job and the SUITE_FAMILY env that feed it.

resolve-matrix.sh looks like the natural home for the replacement. It already flattens to one entry per suite, so it can pick that suite's list and emit the joined string, which leaves the workflow untouched and lets the plumbing above be removed rather than repointed.

#97 tracks the same gap from the other side.
