Use Python installer from the https://www.python.org/

To avoid always writing the Python installation files to this folder, we can just download the installer, check the SHA1 checksum and install Python. This way, on the next Python version iteration, we can just change the SHA1 checksum dictionary and the build can be done. Signed-off-by: Adrian Vladu <[email protected]>
