dbusbind.c patch, fixes possible segfault

[David Hansen]

This one is similar to the previous dbusbind.c patch.  No need to copy
the string and if dbus_bus_get_unique_name () returns NULL strcpy will
segfault.

        * dbusbind.c (dbus-get-unique-name): Remove extra copying of name
        string.
