lib: configfragments: Restrict fragment file checking

The current implementation of the config fragments is too aggressive in
checking files; any file in the fragment directory is checked, including
hidden files or files with weird extensions. In particular, if an editor
is creating temporary backup files when editing, these will be checked
and will almost assuredly fail, which prevents the tool from running.

Add a filter so that only non-hidden files that end with .conf are
checked.
