fa3971011d ci: Exclude subtrees from iwyu (MarcoFalke)
fa8566152a refactor: Bump old copyright header in univalue (MarcoFalke)
Pull request description:
The iwyu CI may modify subtrees when iwyu thinks a header inside a subtree is "associated" (due to the naming).
This happens to not be a problem on current master, but can become a problem if an iwyu-enforced file is renamed or a file is iwyu-enforced in the future.
Fix this by excluding subtrees.
Can be tested by running the iwyu CI on `src/test/fuzz/minisketch.cpp` and seeing a change in `minisketch.h` before this CI fix.
