autoinstall: workaround silly d-i/tasksel bug
It turns out that our preseeded value for tasksel/first (of none) was
being ignored, in turn resulting in the default set of tasks to be
installed in at least Debian systems. Moreover, due to the fact that
tasksel defaults to installing a desktop(!) task on systems where
dmidecode does not return a "rack mount chassis", this resulted into
newly-installed VMs to be provisioned with a full GNOME desktop(!).
The cause for this is a bug in d-i, and specifically in the pkgsel
component. pkgsel is responsible for running tasksel, among other
things, and it does so in the target system. Before doing so, it copies
debconf keys from the d-i debconf database to the target system's
debconf database. However, it only copies a very specific set of
filtered keys (language, country, keymap, username) that does not
include tasksel keys. In other words, tasksel runs on the target system
with no tasksel/* values pre-set at all, despite the package having
explicit support for preseeded installations (tasksel/first and
associated comments in tasksel.pl/tasksel-debconf).
Fix this by exploiting pkgsel's pre-hook mechanism and adding a
debconf-copydb from d-i to target, specifically for tasksel keys.
