[SECURITY] Fedora 26 Update: augeas-1.8.1-1.fc26

A library for programmatically editing configuration files. Augeas parses configuration files into a tree structure, which it exposes through its public API. Changes made through the API are written back to the initially read files. The transformation works very hard to preserve comments and formatting details. It is controlled by ``lens’’ definitions that describe the file format and the transformation into a tree.
