[PATCH openbmc] python-dbus dbus.Byte.__str__ produces broken utf8

[OpenBMC Patches]

From: Brad Bishop <bradleyb at us.ibm.com>

Byte to string simply copied the byte, which isn't valid
utf8 for non ascii values.  Since dbus.byte is an int subclass,
should just be using int's __str__  implementation anyway.
