MacOS: Update the build environment to gtk 3.24.3 - switch to macports

The MacOS build does not recognize the Wacom pen due to a problem
which is fixed in gtk 3.24.23. I did not manage to create the
build environment with jhbuild so I switched to macports. The Readme
explains how to create the build environment. The gtk-mac-integration
and the gtk-mac-bundler is still used, i.e. this build produces an
application bundle which runs standalone.

+# How to build for MacOS
+
+The MacOS build will build most prerequisites via macports. Some updated versions are installed via the manual configure/make/make install. The build environment is located in $HOME/gtk/inst for historical reasons. You need to have Apple XCode installed.
+
+```
+cd mac-setup
+./installmacports.sh
+./cleanmacports.sh
+./build-gettext.sh
+./build-mac-integration.sh
+```
+
+Then your build environment is ready and you can create the app bundle
+
+```
+./complete-build.sh $HOME/gtk
+```
