bugprone-argument-comment: ignore mismatches from system headers

As of 2a3498e2, we ignore parameter name mismatches for functions
in the `std::` namespace, since those aren't standardized. It seems
reasonable to extend this to all functions which are declared in system
headers, since this lint can be a bit noisy otherwise
(https://bugs.chromium.org/p/chromium/issues/detail?id=1191507).
