Picture missing in About dialog on cocoa ui

[Programmingkid]

Hello, now that the code to add the icon to QEMU has been restored for Mac OS, 
I think it is time to revert patch e31746ecf8dd2f25f687c94ac14016a3ba5debfc. 
This patch was made to fix the missing icon in the About dialog but it doesn't 
seem to work any more. I do not see a picture in the About dialog on Mac OS 
11.1. The easiest fix for this issue is to revert the mentioned patch. When I 
ran 
'git revert e31746ecf8dd2f25f687c94ac14016a3ba5debfc' the picture in the About 
dialog appeared again.
