Merge #13544: depends: Update Qt download url

2fca656 depends: Update Qt download url (fanquake)

Pull request description:

  Qt has moved the 5.7.1 downloads from the [official_releases](https://download.qt.io/official_releases/qt/) directory to it's [archive](https://download.qt.io/archive/qt/).

  ```

  ```

  This updates the qt download url in depends so we aren't always falling back on [bitcoincore.org/depends-sources](https://bitcoincore.org/depends-sources).
