[PATCH 1/1] remove all newly installed packages after localepurge

[PATCH 1/1] remove all newly installed packages after localepurge

['Felix Moessbauer' via isar-users]

To perform the localepurge, we install the localepurge package, run the
command and then remove it again from the rootfs. In case the set of
newly installed packages intersects with the set of suggested packages
from all previously installed packages, the intersection is not removed
on autopurge (as apt internally does not track why a package was
installed). However, we want these packages to be removed, as we never
intended to install them in the first place (except for the localepurge
operation).

We fix this by tracking which new packages will be installed when
installing localepurge and then remove exactly these.

One example package that is affected in the base image is "perl".

Ah, nice. I recall having seen this inconsistency before but was too
lazy to fix it...
