Build only 'reasonable' combinations of APP/MEMORY

There's no point in building a DFU loeader that is to be flashed
via DFU - nor is there really any need for regular cardem/trace
that can be flahsed directly without DFU.  If anyone needs those,
they can still build them - but let's not confuse the average other
user.
