missing-breaks does not take diversions into account

For initramfs-tools, the newly enabled missing-breaks job reports:

[ERROR] Missing Breaks/Replaces found
[ERROR] initramfs-tools conflicts with live-tools files: {'/usr/share/man/man8/update-initramfs.8.gz', '/usr/sbin/update-initramfs'}

but live-tools diverts both of these files.

I realise it's probably hard to detect these diversions, but I don't think we should just disable the check entirely for packages that are affected by diversions.

Can you add some kind of exclusion mechanism?
