merge: pass mergeresult obj in _forgetremoved() (API)

Instead of returning a dict of actions and then updating it, let's pass the
object directly and update it there.

This makes `updateactions()` on mergeresult unused and this patch removes that.

After this patch, we have couple of methods left on mergeresult class which
still exposes the internal dict based action storage.

which(1) could exit nonzero, but that's fine because we'll still end
up without a valid executable, so we don't need to check $? here.

Run each fuzzer using dummy.cc as a fake input, to make sure it runs
at all. In the future we should instead unpack the corpus for each
fuzzer and use that instead.
