Fix DocOpt deserialization type bounds

This is wrt https://github.com/docopt/docopt.rs/pull/222

DocOpt does not support deserializing borrowed types.

This change was reverted in
https://github.com/docopt/docopt.rs/commit/7292a374e69afb192bb7aaa00f9d9f4afebc200d
because it broke crates like Cargo etc.
