plugins: Remove old macOS version ifdefs

8dd20dfd335dd07d2f1678c9cdf67894e09beab4 introduced an explicit check
for the available macOS SDK, meaning that we can be sure that the macOS
13.1 SDK is available. As such, we do not require ifdef guards for the
availability of functions that are older than 13.1.
