This is required to ensure that SELinux is configured properly while
building. It fixes the problem with building tar, and should be
installed in the other image types for consistency.
Resolves: rhbz#1645189
(cherry picked from commit 99d867db65)
Since these images can be used to create multiple machines, they should
not have a unique machine-id attached to them. Replace /etc/machine-id
with an empty file so that it will be regenerated at boot time.
This does pretty much the same things as the AMI compose type, but also
replaces NetworkManager with the Azure linux agent.
