Update our git security patch for 2.10
The updated patch is not any functionally different than the previous, and the 2.8 patch we created does work, but requires a fuzz factor of 1
The original patch here: http://public-inbox.org/git/20161201090336.xjbb47bublfcpglo@sigill.intra.peff.net/
Applies without any fuzz to git 2.10.2 and only with offsets of <30 lines
So this here is the exact same patch, with only the offsets updated to match git 2.10.2
