  A few fixes for release-tools/stage-release.sh

Correcting these issues:

- The update branch and release branch were created each on different sides
  of a 'next_release_state' call, which made them differ even though there
  shouldn't be any difference (i.e. --branch was given or implied).
- Running 'do-copyright-year' was done after configuration, and may change
  Configure, which means that the following 'make' call may reconfigure and
  intentionally fail, causing release staging failure.
- In the metadata, the 'staging_update_branch' entry was set to the original
  update branch.
