From: Srinuvasan A <srinuvasan.a@siemens.com>

In present implementation we are using sbuild/schroot to build the
packages, this schroot created via sessions during package build, and
immediatley vanish once build the packages.

Some of the downstream projects uses this chroot at many
places for doing some postprocessing the meta data based on the chroot
path, but unfortunately we cannot refer this path due to creating the
chroot via session.

Hence install the required packages in persistence sbuildchroot, to
access isar-apt and other directories we introduces the sbuildchroot
class.
