fix(loop): add runtime fixes for gsettings and GPU libraries

- Add LD_LIBRARY_PATH to wrapper so Electron GPU process finds bundled libEGL.so.1
- Add glib.bin to buildInputs and wrap gsettings into PATH
- Create versioned symlinks for bundled libEGL.so and libGLESv2.so
- Clean up formatting in package inputs
