--recursive option does not find .py files in sub-directories of packages

[GrimzEcho]

Bug description

When running pylint --recursive=y on a directory that contains both a package and a sub-directory, pylint correctly locates and lints all py files, both those in the non-package sub-directory and those in the package.

However, when running pylint --resursive=y on a package that contains both a sub-package and a sub-directory, pylint will not locate or lint any files in the sub-directory.

Example structure:

- tmp
  - src1
    - my_package
      * __init__.py
      * foo.py
    - scripts
      * bar.py
  - src2
    * __init__.py
    - my_package
      * __init__.py
      * foo.py
    - scripts
      * bar.py

The only difference between src1 and src2 is that src2 is a package.

Running pylint --recursive=y ./tmp/src1 will find/lint both foo.py and bar.py.
Running pylint --recursive=y ./tmp/src2 will not find/lint bar.py

Configuration

Command used

pylint --recursive ./src2

Pylint output

************* Module src2.package1.foo
lint-test/src2/package1/foo.py:1:0: C0114: Missing module docstring (missing-module-docstring)

Expected behavior

bar.py is linted as intended by #5682

Hey, @BrianHVB 👋

Any chance you have that example structure available as a repo?

Thanks!

@scorphus - Thanks for adding a sample repo. I was on vacation for the past couple of weeks and just saw this today.
