Populate the deferred trigger queue.

When dpkg is called with a specific set of packages to act on, we might have packages pending trigger processing. But because there are frontends that do not perform a final «dpkg –configure –pending» call (i.e. apt), the system is left in a state with packages not fully installed.

We have to populate the deferred trigger queue from the entire package database, so that we might try to do opportunistic trigger processing when going through the deferred trigger queue, because a fixed apt will not request the necessary processing anyway.

XXX: This can be removed once apt is fixed in the next stable release.
