Banish Jetpack's Branding from Twitter Cards

See twitter convo at ​https://twitter.com/ericandrewlewis/status/571918662417944576

Twitter pulls this from the twitter:site meta tag, which defaults to @Jetpack. You can override with something like this:

function tweakjp_custom_twitter_site( $og_tags ) {
    $og_tags['twitter:site'] = '@wordpress';
    return $og_tags;
}
add_filter( 'jetpack_open_graph_tags', 'tweakjp_custom_twitter_site', 11 );

I didn't put it in patch form because I figure a lot more cool stuff could be done with it, e.g. a mu-plugin that sets the twitter:site to a twitter account based on what site is in question and/or if one is set manually in Setting->Sharing (e.g. @wordcamp only if the tag still equals @jetpack in the event a local camp didn't change the setting (if they're allowed to?), @wordpress, @bbpress, etc).

Left this as General as it could be Instance wide.
