pass --force-remove-essential to dpkg only if needed
APT (usually) knows which package is essential or not, so we can avoid
passing this force flag to dpkg unconditionally if the user hasn't
chosen a non-default essential handling obscuring the information.
(cherry picked from commit d3930f8716f439c229cd3d11813823d847a2ecff)
