.github/workflows: Simplify and unify build tests

- Use a single definition for both gcc and clang tests, by using a matrix.
- Remove redundant installation for packages present in the CI system.
- Remove version printing for uninteresting programs.
- Trigger for all branches, so that MRs can see results on non-master.
