Correct logic for -Wno-unknown-warning-option (#58523)

* Correct logic for -Wno-unknown-warning-option

It looks like both AppleClang and LLVM Clang use
-Wno-unknown-warning-option instead of -Wno-unknown-warning, so this
updates the logic from b1e5ada to match that. It'd probably also be
possible to just add both -Wno-unknown-warning and
-Wno-unknown-warning-option, but who knows.
