zig cc: add -Wno-overriding-t-option to clang on darwin
This avoids a warning that sometimes occurs when providing both a
-target argument that contains a version as well as the
-mmacosx-version-min argument. Zig provides the correct value in both
places, so it doesn't matter which one gets overridden.
