eb deploy doesn't zip symlinks-to-directories

[khaidirsh]

Description

Symlink to directory not found in zipped application.

Seems commit 790cde6 produces this issue, because as Python documentation about os.walk:

... dirnames is a list of the names of the subdirectories in dirpath (including symlinks to directories, and excluding '.' and '..').

Thus, the mentioned commit has removed the process of including symlinks-to-directories into the zip.

Steps to reproduce

1. Create directory as such:

folder_a/
├─ folder_b/
│  ├─ file_b
file_a
symlink_to_folder_b

2. Run eb deploy

Observed result

symlink_to_folder_b fully skipped (not found in debug log)

...

2024-02-13 22:46:20,068 (INFO) eb :   +adding: ./folder_a/folder_b/file_b
...

Expected result

Symlink to directory added to application zip.
