Certain package upgrade operation extremely slow

[Staudey]

After nodejs was made into a virtual package recently, it was noticed that the upgrade to the new package(s) takes an obscene amount of time (in some cases almost 10 minutes, even on an SSD). Similar things were observed after the llvm package restructuring.

Test case:

1. Uninstall nodejs-20 and nodejs (if installed)
2. sudo eopkg it https://packages.getsol.us/unstable/n/nodejs/nodejs-20.18.0-122-1-x86_64.eopkg
3. sudo eopkg up
