Subject: [PATCH] CMake: clear stale MaxMindDB cache entries if needed

On macOS with Homebrew, the version is included with the library path.
On updates, the old MAXMINDDB_LIBRARY is invalidated. However
ws_find_package only checks MaxMindDB_LIBRARY. Windows has a similar
problem. Make sure to clear the stale value such that newer versions can
be found, fixing the build.

Fixes #17069
