Remove redundant packages concept document

The packages concept came from the old wiki. It more or less duplicates the
content listed in the "Platform APIs and Services" architectural document, but
also lists a number of packages that have long since been removed from Apertis.
Perform a quick tidy up, moving any potentially useful/relevant information to
the architectural document and deleting the packages page.

-This page lists some packages found in Apertis images, not all of which
-are present in typical Linux distributions. Standard Linux components
-such as D-Bus and systemd are also listed here if they are used
-extensively by Apertis.
-
-Many Apertis packages are named after sites in the UK where significant
-Roman archaeological hoards were found.
-
-Each of these packages is classified according to these properties:
-
-  - is it a system service (its scope is the whole system) or a user
-    service (its scope is one specific user)?
-  - is it part of the platform (like dbus-daemon), a built-in
-    application bundle, or a store application bundle?
-  - if it is part of the platform, is it available to store application
-    bundles, or only to the platform and built-in applications?
-
-See [Glossary]( {{< ref "/glossary.md" >}} ) for details of those terms.
