debugutils: nicer printing of caps features

Browse Source 
Only print interesting caps features, don't
append (memory:SystemMemory) to all caps,
which makes them much more unwieldy and
harder to read. Also use internal function
to get caps features so that our printing
has no side effects on the caps.
