Remove lint exclude for directory permissions

This removes the linting exclusion for warning about directories being
created with too open of permissions. We only had one instance of a
directory being created with 755. This does not appear to be needed.
Permissions changed to 750 and golangci-lint exclusion for the warning
is now removed.
