macOS: don't try to declare implementation of NSApplicationDelegate

Browse Source 
There's no run-time representation of `NSApplicationDelegate`, so
trying to declare it ands up adding NULL as a protocol to the
Objective-C class for the application delegate.

Adding NULL that way leads to a crash on 10.12.1+ with TouchBar
support.

Closes racket/racket#1520
