Open Graph: add AIOSEO back to the list of conflicting plugins

A few months ago, we removed All In One SEO from our list of conflicting plugins in 48573a9f0d4616e22ea8c11ce197570c656b2fda, since the plugin authors had added a check for our OG Tags and Twitter Cards, allowing site owners to deactivate Jetpack's OG tags from the AIOSEO plugin options.

Unfortunately, that option doesn't seem to work. That consequently creates a duplicate set of tags when both Jetpack and AIOSEO are active and set to output OG Tags and Twitter Cards.

I've contacted the AIOSEO team to let them know about the issue, and proposed a patch. 
- https://plugins.trac.wordpress.org/ticket/2304
- https://twitter.com/jeherve/status/523394507594031104

Until that patch is released, I think we should add AIOSEO back to the list of conflicting plugins to remove our tags when the plugin is active, and avoid any issues.
