formula: allow std_cmake_args to take parameters

We have a handful of of formulae that do `std_cmake_args.reject` to
override some of flags (e.g. emscripten, icemon, ortp, qt, klee,
watchman).

Let's try to simplify some of this code by allowing these formulae to
override these flags by passing arguments to `std_cmake_args`.

While we're here, let's update the type signature of `std_cargo_args`.
