Remove border and padding from iframes in fullscreen

This restores two rules dropped in the spec sync:
https://codereview.chromium.org/974783002

Without the border:none rule,
http://html5-demos.appspot.com/static/fullscreen.html gets a 1px white
border in fullscreen, which looks particularly odd due to the rounded
borders in this demo.

Without the padding:0 rule, https://play.google.com/store/movies?hl=en
gets a 60px white padding at the top of the fullscreen iframe, which is
clearly not the intended design.
