dictclient: monkeypatch DICTError

The Ruby/DICT library is so tightly coupled with the rdict client that
its errors exit on initialize, instead of letting the lib user do that.
This makes those errors untrappable from the code.

Fix by monkeypatching DICTError to just act like the other exceptions in
Ruby.
