Remove local patching/symlinking of macOS build.

In the past various workarounds have been put in place to move/copy/symlink
files in the macOS app build to make PyQt work and let us sign it.

As of https://github.com/pyinstaller/pyinstaller/pull/7619 our downstream
patching should not be required.

The application seems to run fine.
The app size is 155 MB.
Signing is still to be verified.
