Subject: [PATCH] openvswitch: add target python handling

Allow the build to specify a path for the python instead of reusing
the PYTHON variable which can lead to inconsistencies if we are cross
compiling. The TARGET_PYTHON variable will be used for script
substitutions to ensure the scripts will be able to properly execute
if the target system has a different path for the python.
