Py_NoSiteFlag is not needed since Python 3.8

Python since 3.12 prints warning about Py_NoSiteFlag is deprecated. It
seems that variable is not needed since Python 3.8, since it sets in
such cases directly config.site_import variable few moments later.
Move using deprecated variable to versions before that flag in config
could be used only.

This should fix warning like:

pythonmod/pythonmod.c: In function 'pythonmod_init':
pythonmod/pythonmod.c:359:7: warning: 'Py_NoSiteFlag' is deprecated [-Wdeprecated-declarations]
