file_server: Accept files args in one-liner of Caddyfile matcher (#3298)

Previously, matching by trying files other than the actual path of the
URI was:

    file {
        try_files <files...>
    }

Now, the same can be done in one line:

    file <files...>

As before, an empty file matcher:

    file

still matches if the request URI exists as a file in the site root.
