Etienne Champetier f26cc9f75b Only use stat get_checksum: yes when needed (#7270)
By default Ansible stat module compute checksum, list extended attributes and find mime type
To find all stat invocations that really use one of those:
git grep -F stat. | grep -vE 'stat.(islnk|exists|lnk_source|writeable)'
