Fix incorrect upgradable listing in "apt list" (thanks to Michael Musenbrock)

The "apt list" command was using only the pkgDepCache but not the
pkgPolicy to figure out if a package is upgradable. This lead to
incorrect display of upgradable package when the user used the
policy to pin-down packages. Thanks to Michael Musenbrock for the
initial patch.
