package/pkg-python: use SETUPTOOLS_USE_DISTUTILS=stdlib

Browse Source 
# ipython -c 'import math; math.floor(12.3)'
-sh: ipython: not found

ipython use a wrong shebang on the target:

 # head -n 1 /usr/bin/ipython
 #!/home/kubu/buildroot/testsuite-master/TestIPythonPy3/host/bin/python

The issue come from python3-setuptools 60.0.0 that changed
SETUPTOOLS_USE_DISTUTILS default value from stdlib to local [1] to use
its local copy of distutils. This is actually a "breaking" change [2].

We have to override SETUPTOOLS_USE_DISTUTILS to the previous value
"stdlib" to fixes the issue.

While at it, use distutils from stdlib for the host.
