depends: Update URL for qrencode package source tarball

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
page instead.

The diff between the source trees is immaterial.
