be >= the version of the langpack instead of =.
Will allow langpacks from -release to work with firefox-esr updates in
-stable, otherwise packages updates in -stable required one to uninstall
the corresponding langpacks (which dont get updates, as technically a
langpack cant have security issues)
Tested working fine with a 68.5.0esr fr langpack with a 68.6.1esr binary.
