As of version 3.0.0 tldextract requires filelock during runtime. [0] In
nixpkgs tldextract was bumped from version 2.2.3 to 3.1.0 in
5b2d82451f034b2ce30eae12b3cf3f860381279b without actually updating the
dependencies breaking packages such as qutebrowser.
This fix is part of this series to verify that bumping qt5 to 5.15.2
actually fixes the crash caused by WebRTC [1].
