Remove unnecessary relocations 2022 edition

Qt 4 changed the moc string table format following http://library.bagrintsev.me/CPP/dsohowto.pdf Section 2.4 and we have since added qOffsetStringTable to make applying this technique simpler. Yet, we have new unneeded relocs creeping in all the time, so we should probably schedule a round of review this year.

This epic is here to collect items that, for some reason, cannot be fixed ad hoc.

I'm attaching Drepper's relinfo.pl script for progress reporting.

And here's a shell script to find where relocs originate: https://stackoverflow.com/a/19338343/134841
