Merge bitcoin/bitcoin#33494: depends: Update URL for qrencode package source tarball

93a70a4 depends: Update URL for `qrencode` package source tarball (Hennadii Stepanov)
6de8051 depends: Use hash instead of file name for package download stamp (Hennadii Stepanov)
46135d9 depends: Drop redundant check for downloaded file (Hennadii Stepanov)
7719789 depends: Fix `$(package)_fetched` target (Hennadii Stepanov)

Pull request description:

  The https://fukuchi.org/ homepage no longer links to the source tarball, and previously available files appear to have been removed. The homepage now instructs users to download source tarballs from the GitHub [releases](https://github.com/fukuchi/libqrencode/releases) page instead.

  The diff between the source trees is immaterial:

  **UPDATE 2025-09-30**

  A few commits have been added:

  1. The first commit fixes the `$(package)_fetched` target, which erroneously succeeds on the second run after a failure on the master branch:
  ```
  $ gmake -C depends clean-all
  $ gmake -C depends qrencode_fetched FALLBACK_DOWNLOAD_PATH="https://fallback.invalid"
  $ gmake -C depends qrencode_fetched FALLBACK_DOWNLOAD_PATH="https://fallback.invalid"
  $ echo $?
  0
  ```
  With the first commit applied:
  ```
  $ gmake -C depends clean-all
  $ gmake -C depends qrencode_fetched FALLBACK_DOWNLOAD_PATH="https://fallback.invalid"
  $ gmake -C depends qrencode_fetched FALLBACK_DOWNLOAD_PATH="https://fallback.invalid"
  $ echo $?
  2
  ```

  2. The second and third commits allow the depends build subsystem to detect when the source tarball content has been modified and needs to be re-downloaded, even if the file name remains the same.
