Describe the bug
Starting the run-everywhere AppImage doesn't work.

To Reproduce
Try to start that on any system that has no libfuse2 (still allows to run extracted) or does not use glibc (does not start at all, error message shown in ldd).

Expected behavior
Should open.

Additional context
If I understood AppImage/AppImageKit#877 correctly then the AppImage needs to be built differently using appimagetool --runtime-file with the type2-runtime.
