  gmmproc: Fix compatibility with gtkmm 3.24.2

  * tools/m4/class_shared.m4: Check if __FUNC_DECORATION__ is defined.
  class_gtkobject.m4 in gtkmm 3.24.2 and older does not define it.
  Fixes #82
  
  It's not necessary to push this patch to the master branch.
  That branch is not compatible with gtkmm-3 anyway.

  Meson build: fix is_os_cocoa detection

  The previous check didnt work as the compiler choked on the Objective-C code
  that was dragged in by the Cocoa headers.
  
  This patch simplifies things by simply asking what system the host is
  running on.
