bundle2.unbundlepart: implement seek()

This implements a seek() method for unbundlepart.  This allows on-disk bundle2
parts to behave enough like files for bundlerepo to handle them.  A future
patch will add support for bundlerepo to read the bundle2 files that are
written when the experimental.strip-bundle2-version config option is used.
