[PATCH 0/1][SRU M/N/U] Fix secure execution regression on s390x

== SRU Justification ==

Impact: To allow secure execution the S390X_UV_UAPI driver is a critical
requirement. For 22.04/Jammy LTS we backported the driver and enabled it
as built-in. It seems 22.10/Kinetic also had this enabled. But then in
later releases this option flipped back to 'n'.

Fix: Turn this back on (built-in) in the annotation file. Note, this
patch is made against Mantic. Noble and Unstable might need adjustments.

Test case (on a s390x instance):
#> cat /boot/config-$(uname -r) | grep UV_UAPI
CONFIG_S390X_UV_UAPI=y

Regression potential: If anything goes wrong, then likeliy within secure
execution bounds.
