Bug description:
[Impact]
Atari partition tables have very broad specifications, and can spontaneously
show up on uncleared disks with "garbage" data. There have been reports of
misinterpreted AHDI partition tables before (see [0] and [1]), usually as an
unintended side-effect of using non-zeroed disks. Users of this specific
partition scheme are unlikely to be on AWS instances, so we should disable them.

[1] https://mail-index.netbsd.org/port-atari/1995/11/19/0001.html
[Test Case]
Ensure that CONFIG_ATARI_PARTITION is not set in /boot/config-$(uname -r)
[Fix]
Unset CONFIG_ATARI_PARTITION in debian.aws/config/config.common.ubuntu
[Regression Potential]
There could be unexpected dependencies on Atari partitions that are impacted
by this change. Considering Atari hardware hasn't been produced in a long time,
and is unlikely to be used in AWS instances, the regression potential should be
very low.
