python: fix patch removing multiarch support for host python

Patch removing multiarch paths from build should be applied only when
Python is built for target, but not for host. When the paths are removed
during host build, host python throws some ugly errors when importing
some hashlib modules. Also it reports that modules crypt and nis failed
to build (tested on Ubuntu 14.04 host).
