    Check if a file is within the passed in path and if so, returns the
    relative mod path from the one passed in.

    If the filename is no in path_to_check, returns None

    Note this function will look for both abs and realpath of the file,
    this allows to find the relative base path even if the file is a
    symlink of a file in the passed in path

    Examples:
        _get_relative_base_path("/a/b/c/d.py", "/a/b") ->  ["c","d"]
        _get_relative_base_path("/a/b/c/d.py", "/dev") ->  None
