lxc-debian: improve detection of official architectures

Browse Source 
An official architecture is not always available in testing. New
architectures get added to unstable first, and only some time after that
they *may* get added to testing as well. This is just now happening with
riscv64, and checking whether it's available in testing will *not* give
the correct answer for the question "is this an official Debian
architecture?".

Also, since debian-ports only contain unstable, just refuse to use
debian-ports if not creating an unstable/sid container.
