kiwix-desktop appimage creation under jammy

- Switched from linuxdeployqt to (linuxdeploy + linuxdeploy-plugin-qt)

- Eliminated custom creation of the AppDir & most manual copying of
  some stuff into it (trusting linuxdeploy to do everything needed
  for the correct operation of the appimage). Note, however, that
  nss/ libs are no longer bundled with the appimage (libthai.so is
  forcefully bundled via a special option to linuxdeploy).
