Subject: List held packages in dpkg

The completion for dpkg -L/--listfiles does not list held packages when
grep-status (from dctrl-tools) is installed. This is because the
grep-status _comp_dpkg_purgeable_packages cares about the dpkg package
selection states (install/hold/deinstall/purge) while the other version
only cares about the dpkg package states (installed/unpacked/etc).

There is a similar issue for the _comp_dpkg_installed_packages function.

The fix for this is quite simple, just remove install/deinstall from
the arguments to the -FStatus options.
