Official statement

Google is capable of identifying social media sites and marking all links coming from these sites as nofollow on its end, even if these sites use dofollow links. It would be quite surprising for a large social network site to exist with dofollow links that Google hasn’t already marked as nofollow internally.

TL;DR

Google applies a nofollow to all links coming from social media sites, even if those links are dofollow. For SEO, this means betting on these links to improve internal PageRank is futile.
