Revert "fetch-kde-qt.sh: get hashes from metadata"
This reverts commit 4b7d9dc868.

The KDE project has changed their source index pages so that the links to
package metadata files are generated by JavaScript after the page loads. As a
result, wget is no longer able to recursively fetch the package metadata
automatically.
