Dropping global package-lists entirely, only local package lists within the config tree are support.

live-boot pulls in eject and file through recommends,
live-config pulls in user-setup and sudo through recommends,
gnupg is pulled in as include during bootstrap on ubuntu.

We don't need these packages by default, and if users are
building with recommends disabled, then they have to make
sure these are pulled in too.

This is the more consistent handling than to explicitly
force all of these in all live images.

For the default images, we're maintaining their config trees in
git repositories now. So they're not needed anymore.

For people wanting to build e.g. a GNOME image in a 'quick&dirty'
way, in the past, they used something like 'lb config -p gnome'.

Since we do want to get away with all automagics like this where
we need to maintain the package list eventhough tasksel is already
doing that (and more), we're now needing people to create a package
list, e.g.

  # echo 'task-gnome-desktop' > config/package-lists/gnome-desktop.list.chroot

This is consistent with the package handling where we dropped the
'lb config --packages' in favour for the same mechanism for package lists.

With dropping global package lists finally, we'll have consistency
and same workflow for everything soon.

Dropping global binary includes and moving binary local-includes to includes, just as with chroot includes and local-includes.

Fixing up inclusion of functions while allowing local usage of live-build with different file layouts.

This package list has had a spelling typo since its initial
commit. Nobody has ever reported that and the official
live-build package in ubuntu does not ship these lists either.
Apparently nobody uses them, so we can remove them to improve
quantity/quality ratio.

Removing losetup-lukshome.chroot example hook, obsoleted by live-boots new persistence implementation.
