Auto merge of #13412 - ehuss:update-git2, r=weihanglo

Update git2

This updates git2 primarily to pull in the update for libgit2 1.7.2 which fixes three security issues. `@weihanglo` did some investigation, and it looks like cargo may be susceptible to one of them with rev parsing. I am uncertain of the severity, but the CVE seems to imply that it is mainly a denial-of-service with an infinite loop from a well-crafted spec.

See https://github.com/libgit2/libgit2/releases/tag/v1.7.2 for more information.
