exthelper: drop the addattr() decorator

Yuya pointed out that this goes against the typical advice to not add attributes
to classes[1].  The evolve extension still uses this a handful of times, so
maybe it should be brought back in the future if a general use is found.  But it
isn't nice to have a new helper API that can lead to easy problems.
