Why I did it
Recent systemd upgrade from #7228 requires an extra cmdline parameter for dockerd to start properly.
Updating boot0 was missed as part of the systemd upgrade change.
How I did it
Just added the missing cmdline parameter in files/Aboot/boot0.j2
This change fixes #7372
How to verify it
Boot the image and dockerd should start normally.
Which release branch to backport (provide reason below if selected)
I'm not sure if systemd will be upgraded in 202012.
If it is, this change will have to be cherry-picked.
