python-jsonpatch: fix do_install failure with py2 build

The following error is seen when do_install is run

| UnicodeEncodeError: 'ascii' codec can't encode character u'\xf6' in
| position 16: ordinal not in range(128) ERROR: python setup.py
| install execution failed.

This is reported in the upstream project as part of pull request #81
https://github.com/stefankoegl/python-json-patch/pull/81

Since a release is not yet available with the required fix we must
apply the fix as a patch.
