Title: CSS: avoid notices to be displayed over WP submenus

I couldn't always reproduce, but here is what sometimes happens with Updated messages when Jetpack is active:

It seems to be caused by an old `z-index` rule that's been in Jetpack from the beginning. I ran a few tests after removing it and it doesn't seem to break anything, but I'm no CSS expert and my tests didn't include older browsers.

The problem was reported here:

We should also keep an eye on [26567-core](http://core.trac.wordpress.org/ticket/26567), since it's a related issue.
