UBUNTU: [Packaging] Turn on ODM support for amd64

BugLink: https://bugs.launchpad.net/1912789
Now there is the support in place let us turn this on for amd64. This is
added as enabled generally in the config because otherwise updating the
config for drivers depending on it would not work. It is changed at
build time for arches which have not enabled it. Also it will
automatically go away for backports.
