meta-openpower: croserver: use pythonnative

croservers config script requires python2.  Use the yocto built python2
instead of the build host python2, for cases where the build host does
not have python2 installed (or env python is python3).

(From meta-openpower rev: 1f32015926ead63cea102bbbd67d452e9685f165)
