epriestley a4e8fd2289 Wait for the Git client to disconnect before exiting in Git SSH workflows
Summary:
Ref T2230. Very rarely, even though we've flushed the connection and sent all the data, we'll close the connection before Git is happy with it and it will flip out with an error like this:

  fatal: The remote end hung up unexpectedly
  fatal: early EOF
  fatal: index-pack failed

This is hard to reproduce because it depends on the order of read/write operations we can't directly control. I only saw it about 2% of the time, by just running `git pull` over and over again.

Waiting for Git to close its side of the connection seems to fix it.

Test Plan: Ran `git clone` a ton of times without seeing the error again. Ran `git push` a ton of times with new commits.
