common-source: fix create-spdx handling

- do_create_spdx does have to wait till the shared source
  tree is properly populated
- override the spdx class code detection to determine
  if sources are under work-shared.
  the core code does only look at WORKDIR, which isn’t
  overridden in every case, more likely only S and B are
  touched, which make the spdx class code assume that
  these are per-workdir sources and starts to remove the
  shared sources via bitbake’s cleandirs settings.
  Avoid that by let the code always handle recipes including
  common-source as shared sources.

Relates to #721
