fileserver: Redirect within the original URL (#4179)

This commit changes the file_server directive to redirect using the
original request's URL instead of the possibly trimmed URL. This should
make file_server work with handle_path.

This fix is taken from mholt's comment in
https://caddy.community/t/file-servers-on-different-paths-not-working/11698/11.
