[Buildroot] [git commit] python-setuptools: Add missing $(TARGET_DIR) to PYTHONPATH

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=0b363ba5f389b3744937658f40f1e796e5447db3
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The $(TARGET_DIR) variable is required when building
python-setuptools for the target otherwise the build system detects
the host installation which leads to permission error problems
like these:

Setuptools installation detected at /usr/lib64/python2.7/site-packages
Renaming /usr/lib64/python2.7/site-packages/setuptools-0.9.8-py2.7.egg-info to
/usr/lib64/python2.7/site-packages/setuptools-0.9.8-py2.7.egg-info.OLD.1377005697.88
OSError: [Errno 13] Permission denied

Moreover, remove the PYTHONPATH variable for host variant since it's
not needed.
