[Buildroot] [PATCH] package/dbus-python: fix build failure due to wrong auto-detected extra libs

[Giulio Benetti]

Using Python 3, during configuration, if PYTHON_EXTRA_LIBS is not
defined, ./configure will launch a python script to retrieve LIBS and
SYSLIBS variables, but this is done using host-python resulting in
obtaining libraries that are not present in target. So while trying to
link configuration test it fails complaining it can't find a
library(i.e. libintl).

Set PYTHON_EXTRA_LIBS the same as PYTHON_LIBS to be sure host libs are
not used at all.

Fixes:
