cmd/go: disable password prompt when running git

This fix only works on Git 2.3.0 and later.

There appears to be no portable way to fix the earlier versions.
We already run git with stdin closed, but on Unix git calls getpass,
which opens /dev/tty itself. We could do package syscall-specific
things to get /dev/tty invalidated during the exec, but I'd really
rather not. And on Windows, Git opens "CONIN$" and "CONOUT$"
itself, and I have no idea how to invalidate those.

Fix the problem for newish Git versions and wait for people to update.
Best we can do.

Fixes #9341.
