Fix arrayobject.h path on Debian based distros
On Debian Linux and its derivatives such as Ubuntu and LinuxMint, Python packages installed through the package manager are kept in a different non-standard directory called 'dist-packages' instead of the normal 'site-packages' [1]. To detect the Linux distribution the 'platform' library (part of the Python stdlib) provides a function 'platform.freedesktop_os_release()' that parses a standard file '/etc/os-release' available in most Linux distributions [2]. However this function is rather new (Python >= 3.10) and unavailable in most python installations, so the core of its functionaly was reimplemented here.
