interpreters/python: create Python's config files dynamically

Browse source 
The `Setup.local` and the `config.site` files are used by Python's
build system to, respectively, enable or disable Python's modules
and set/unset available functions in the target system. These files
are now set according to NuttX's configs, enabling or disabling
Python's features according to the configs set on NuttX.
