import-checker: allow import of child modules from package root

I got the following error by rewriting hgweb/__init__.py to use
absolute_import, which is obviously wrong:

  Import cycle: mercurial.hgweb.__init__ -> mercurial.hgweb.__init__

"from foo import bar" should not make a cycle if "foo" is a package and
if "bar" is a module or a package. On the other hand, it should be detected
as a cycle if "bar" is a non-module name. Both cases are doc-tested already,
so this patch does not add new doctest.
