packages are not recognized as packages if `__init__.py` as it should since python 3.3

I was workig with autoapi and I got weird errors related to relative imports:

astroid.exceptions.TooManyLevelsError: Relative import with too many levels (2) for module 'not_found_404'

I finally realized that all the packages that were not specifcally containing a __init__.py file were simply discarded due to this lines of code:

astroid/astroid/nodes/scoped_nodes/scoped_nodes.py

Line 493 in 580d17c

if self.package:

        if level:
            if self.package:
                level = level - 1
                package_name = self.name.rsplit(".", level)[0]
            elif (
                self.path
                and not os.path.exists(os.path.dirname(self.path[0]) + "/__init__.py")
                and os.path.exists(
                    os.path.dirname(self.path[0]) + "/" + modname.split(".")[0]
                )
            ):
                level = level - 1
                package_name = ""
            else:
                package_name = self.name.rsplit(".", level)[0]
            if level and self.name.count(".") < level:
                raise TooManyLevelsError(level=level, name=self.name)

It turns out that to be considered a package, a folder MUST have an __init__.py file. Can you expand a bit the "package" definition to any folder including python files ?
