multi: Switch to upstream golang.org/x/crypto.

Now that glide is used for version management and a specific commit of
the upstream repository can be locked it is no longer necessary to
maintain a fork of the package specifically to keep a stable dependency.

While here, update the glide dependency for btcutil as well since it was
switched to use the upstream path as well.
