macOS: build googlemaps plugin as fat binary

Browse source 
I couldn't make this to work as a single pass build, so we again do a dual pass
and manually assemble the dylib. This is then copied to a sane spot which
required another attempt to copy it in the CMakeLists.txt - which I added
comments to in order to make sense of the weirdness.
