Rename qurltlds-related files to match the header's move

The header is now in src/network/kernel/ rather than src/corelib/io/,
but the qt_attribution.json got left behind and the update program was
still in a sub-dir of util/corelib/. Renamed the latter to
util/publicSuffix/ (second-layer sub-directory was overkill, util/
isn't crowded and it was the only thing in util/corelib/; and there
was no util/network/).  This is a follow-up to
commit 4f076db3d2
