Merge bitcoin/bitcoin#31011: refactor: move util/pcp and util/netif to common/

fd38711 ci: make CI job fail when check-deps.sh script fails (Ryan Ofsky)
d51edec common: move pcp.cpp and netif.cpp files from util to common library since they depend on netaddress.cpp (Ryan Ofsky)

Pull request description:

  Move util/pcp.cpp and util/netif.cpp to common/ because they depend on netaddress.cpp which is part of the common library. This was causing check-deps.sh script to fail as reported by _fanquake_ in bitcoin/bitcoin#30415 (comment).

  Also make CI fail when the `check-deps.sh` script fails. Previously it would output errors but not cause the job to fail (which was not intended).
