[issue38523] ignore_dangling_symlinks in shutil.copytree does not apply recursively

[Rob nelson]

New submission from Rob nelson :

The ignore_dangling_symlinks attribute in shutil.copytree is not passed down 
recursively, resulting in dangling symlinks located anywhere other than the 
root of the source tree to raise an error.

The line causing the error for 3.9: 
https://github.com/python/cpython/blob/v3.8.0/Lib/shutil.py#L486

Trivial patches and an improved test case for:
3.7: 
https://github.com/veaviticus/cpython/commit/a662ae8a3f85380ec76ed3dfbc778aad8c5ac37a

3.8: 
https://github.com/veaviticus/cpython/commit/64f72c7196243bd3e2cf4136ebbb9f9ffe206750

3.9: 
https://github.com/veaviticus/cpython/commit/e55dd12e558443c350d241d87bf17dfc322dbfcf
