create-relocatable-package.py collects shared libraries used by executables for packaging. It also adds libthread-db.so to make debugging possible. However, the name it uses has changed in glibc, so packaging fails in Fedora 37. Switch to the version-agnostic names, libthread-db.so. This happens to be a symlink, so resolve it. Closes #11917
