[PATCH] OpenNetworkLinux on Ubuntu 20.04.1 LTS

DESCRIPTION.MD

Overview

This patch allows the current ONL master branch (ref. 1537d833) to build on Ubuntu 20.04.1. Without this patch, the following error is observed while building using the docker/tools/onlbuilder environment when targetting armel:

INFO:onlrfs:dpkg-configure filesystem...
DEBUG:onlrfs:Executing:sudo chroot jessie/rootfs-armel.d /tmp/configure.sh
chroot: failed to run command '/tmp/configure.sh': No such file or directory

This patch was created and confirmed working against:
