formula: fix alias/generic/prepend std_cmake_args issue.

Seen in:
https://github.com/Homebrew/homebrew-core/pull/191090#issuecomment-2363215204

There's a missing signature issue here due to the `generic_*` aliasing
we're doing. With prepend, though: this is no longer needed and we can
use `super` instead which is more idiomatic and nicer overall.

This pattern should probably be applied in other places but: let's try
this targetting fix for here first.
