dbus.Byte does not accept single character strings

[Len Ovens]

Using dbus.Byte to create a Byte value for dbus errors out with:
    return dbus.Byte(value);
TypeError: Expected a bytes or str of length 1, or an int in the range 0-255

even with a one character string like 'e' or 'a'. This is likely because python2 strings were char and python3 strings are unicode. dbus.Byte should still accept a str of length 1 and make the needed conversion internally.
