Merge bitcoin/bitcoin#22685: clientversion: No suffix #if CLIENT_VERSION_IS_RELEASE

5100deee58 clientversion: No suffix #if CLIENT_VERSION_IS_RELEASE (Carl Dong)

Pull request description:

  ```
  Previously, building from a release source tarball would result in a
  version string like v22.0.0-<commithash>, but we expect just v22.0.0.
  This commit solves this problem.

  Also use PACKAGE_VERSION instead of reconstructing it.
  ```

  Fixes the underlying problem of #22623

    ACK 5100deee58 - tested that prior the output of `src/bitcoind -version` on the `22.x` branch was `Bitcoin Core version v22.0.0-d3bd5410f64e`, and with this commit cherry-picked it is `Bitcoin Core version v22.0.0rc2`.
