ArchiveBox: Bugfix: docker iframe adds /data/ to url incorrectly

Yes, it is added in there. However, a trailing slash should not (ideally) break anything at all. I will remove it from that line, but I will leave https://github.com/pirate/ArchiveBox/issues/487 open to find a more permanent solution. Thanks!

@cdvv7788 It failed.

docker build . -t archivebox --no-cache

Yes, it should be possible. If you are getting any issue, please let me know and I will check it.

@poblabs https://github.com/pirate/ArchiveBox/pull/486 This should fix the issue.

I will give this a check. This may be related to some changes we made to calculate the path to wget.
