Subject: [PATCH] chatterino2: fix: Could not find the Qt platform plugin
 "cocoa" in ""

wrapQtAppsHook ignores Mach-O binaries [1]. Additionally, wrapQtAppsHook
doesn't look inside $out/Applications [2], which is where chatterino2 is
installed. This means chatterino2 for Darwin/macOS is not wrapped
properly, causing the following error when launched:

> qt.qpa.plugin: Could not find the Qt platform plugin "cocoa" in ""
>
> This application failed to start because no Qt platform plugin could
> be initialized. Reinstalling the application may fix this problem.

On macOS, explicitly wrap chatterino2's executable.
