cocoa: Don't change the NSWindow background color.

Browse Source 
Changing the background color causes the titlebar to blend against it on
modern macOS releases, making all SDL windows look wrong by default. This was
set to make the window not flash white before a GL context is ready, but we
can accomplish this in our window's view's drawRect implementation, too.
