Use more lenient pattern-matching for Webpack files

We currently expect every Webpack manifest to include a stem of `config`
or `conf`. Webpack's configuration docs tell a different story, however.
At least three different filenames are mentioned, none of them even make
mention of a `.config.js` suffix!
