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.

[Test Case]
Ensure that CONFIG_ATARI_PARTITION is not set in /boot/config-$(uname -r)

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.
