 py27-pyobjc, py35-pyobjc: Fix crash on Catalina

 AFAICT the root cause was that PyObjC wrote to a variable mapped to
 read-only memory. Luck would have it that this particular write is
 redundant, so we can “fix” the bug by checking whether the value would
 change, and thus avoid the write — and crash.
