[Buildroot] [PATCH 4/5] package/pkg-python: rely on python wrapper in HOST_BIN_CROSS

[Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>]

Since we now have a python wrapper in HOST_BIN_CROSS, we no longer need
to set all these environment variables from the python-package
infrastructure.

Add HOST_BIN_CROSS to the PATH for target packages, and remove all
environment variables which are already set by the wrapper. Use this
python as the python that is used to run setup.py.

PKG_PYTHON_SYSCONFIGDATA_NAME is no longer used so it can be removed.
