Update expected packages for distroless Mariner

[mthalman]

The latest servicing version of Mariner has caused a change in the expected packages that exist. We verify these expected packages for the distroless version and this new version has caused tzdata to be added and prebuilt-ca-certificates-base to be removed. This doesn't seem right and I'll continue to investigate what happened and log issues if necessary. But these changes update the tests to reflect the current status and unblock the build.

Ok, looks like these changes were intentional to make distroless Mariner a drop-in replacement for Google distroless to better support AKS: microsoft/azurelinux#4247.

The addition of tzdata changes the minimal base image size from 3.3 MB to 4.1 MB.

The "removal" of prebuilt-ca-certificates-base is actually a good thing. That used to exist in the minimal base image but we install prebuilt-ca-certificates which should be a replacement of it but because of distroless being distroless, removal of replaced packages isn't done automatically by the way we install packages. So before we ended up with both packages when all we really wanted was prebuilt-ca-certificates. Now that is happening. So that part is good.
