A prior update config for python2/3 compatibility resulted
in config values being set as unicode rather than strings. This
ended up breaking patching on IPv6 systems, as the lib,
if_nametoindex function used by patching in configuration of its
multicast addresses does not properly handle unicode.
As a result, the patching daemons were unable to communicate with
each other.
This update to tsconfig/config casts the values as str() to
restore it to the previous behaviour.
