    python/sepolicy: Fix get_os_version except clause
    
    This adds more exceptions to be handled by the except clause in
    `get_os_version()`:
    
    * If the `distro` package is not installed, then `import distro` raises
      a `ModuleNotFoundError` exception.
    
    * The distro documentation[1] lists `OSError` and `UnicodeError` as
      exceptions that can be raised.
    
    * Older versions of distro (<= 1.6.0) may also raise
      `subprocessCalledProcessError`[2].
