WIP: archivepublisher: Do not publish disabled architectures for PPAs

PPA publishing only checked whether the DAS was enabled, but not
whether the processor for it was enabled in the PPA; causing PPAs
to end up with two issues:

A. Architecture: all packages appear for disabled architectures.
B. The disabled architectures appear enabled

This change compromises three parts:

1. Not writing indices for disabled architectures
2. Updating the list of indices to exclude disabled architectures

These address the actual publishing, hence point A.

3. Updating the Release file generator to only put the enabled
   architectures in the Architectures field.

This causes APT, for empty or missing Packages files not to warn
about the PPA not supporting that architecture.

YMMV here, in particular, it's likely wrong for i386: We don't want
PPAs to warn when added to multi-arch amd64+i386 system; so we should
likely special case this there.

On the flip side, we may not want to advertise "primary" architectures
as supported that aren't.

Use per-distro-pocket apt-ftparchive caches

The cache databases get corrupted quite regularly, and
this means we need to rescan the debs for all series
in the archive, which is a lot of work.

So switch to per-distro caches instead, actually including
the full pocket. The huge advantage is we never need to
rescan stable release pockets anymore - once scanned we
don't modify their databases anymore as there's nothing
to write.

Implement Valid-Until for security pocket

Implement the Valid-Until field for all security pockets;
including existing ones.

Set the Valid-Until field two weeks after the publication
Date field, and republish the Release file if it will expire
in less than a week.

A similar change probably needs to be made for ESM publishing,
I haven't checked that. This works for the main archive at the
very least.
