When updating a package requires restarting the computer, it is good for Software Updater to show this *before* installation begins. That way, if you need to ration updates for any reason, you can batch together those updates that require a restart, minimizing downtime and installation time.

To allow this, the new Software Updater UI puts a restart icon next to an individual update -- with an explanation below the list of updates -- if that update's debian/control file contains the XB-Restart-Required key.

glibc packages should set this key, but currently do not. Fixing this should be a one-line change.
