http: Don't generate a HTML page with list of shared files.

Right now if you try to access / or /index.html URI, the p2p HTTP
server returns a simple HTML page listing the files currently
shared. This can be witnessed by putting http://1.2.3.4:16725/ into a
web-browser. While this is a convenient development aid, there are
some security- and privacy-problems with it. So just remove it.

BUG=chromium:309708
TEST=Unit tests pass + manual inspection that 404 is returned if
    either of the URIs / or /index.html are requested.
