Use an anchor tag to download the webrtc-internals log.

We used to download the log through a form submission, which is recently
changed in Chrome to have an extra "?" at the end of the URL, which triggers
a navigation instead of a download. The change seems intended and consistent
with other browsers (see the issue for more details). So I'm now using an anchor tag to work around it.
