Please use update-notifier-common instead of update-notifier package

The update-notifier package requires a slew of gnome and desktop-like dependencies, adding a host of bloat and lag to the servers and install process. The actual command used by WPCD is /usr/lib/update-notifier/apt-check which is actually provided by the much less taxing update-notifier-common package.

Here's what I get when asking for update-notifier on a minimal ubuntu image:
