Extract workflows dependencies

- Move build dependencies moved to
  `.github/workflows/build-dependencies.txt` shared among workflows.

- Change `ubuntu-latest` -> `ubuntu-20.04` to avoid unexpected
  runner environment updates in `zloop` workflow.

- Change `ubuntu-20.04` -> `ubuntu-latest` to track changes in
  runner environment in `checkstyle` workflow.

- Kernel buffer is flushed before ZTS invocation to avoid storing
  the same data after each test case run.

- `make` is invoked with consistent set of options to reduce
  clutter in logs.
