[PATCH] Fix mounting of downloads dir into buildchroot

[Jan Kiszka <jan.kiszka@siemens.com>]

setup_root_file_system() mounts most of the required paths buildchroot
needs into its rootfs - except for the downloads dir. But do_build() of
dpkg-base cannot not detect this gap because it tests for isar-apt being
mounted.

To close the gap without causing duplicate mounts, just add the missing
mount to the end of buildchroot do_build().
