That code is (should) not used for loading plugins.  It is used for loading
libgstreamer-1.0, libgstbase-1.0 and libgstapp-1.0.  Unless I'm misreading
something, they all still have the -1.0 suffix to allow parallel
installation?  eg.
https://packages.ubuntu.com/bionic/amd64/libgstreamer1.0-0/filelist

It's not a compile time constant.  You should be able to set it before
calling Gst.init();
