fix ansible galaxy file mangling (#23703)

without this patch, ansible-galaxy will mangle files containing
the archive parent directory name, eg 'owncloud/files/owncloud.cron'
will become 'owncloud/files/.cron'.

The previous code could affect the entire path and even filenames.
If a file path has the top level dir name as a substring, galaxy
replaces it with ''. In one example, the archive top level dir
is 'go', so 'files/go-bin.sh' becomes 'files/-bin.sh'.

Fixes #22572, #23694, #23623
