Let every postmarketos-ui-* package have a link on top that points to
the new UI package reference. Do not put the link in <>, as it was done
with other references, since there's no benefit to it. It doesn't look
better and it doesn't make it easier to click the link or something, I
just did this initially because I saw it in GPL license headers.

This adds a new 'UI' that includes networking support (network manager), firewall (by way
of postmarketos-base-ui), and anything else that will give a basic,
working image without any graphical UI.
The intention is for bpo to build this instead of the 'none' UI. 'none'
UI will continue to be around for mainlining and testing purposes.
