This is a temporary fork of Go 1.13's os/exec package, to work around https://github.com/golang/go/issues/36644.
The main modification (outside of removing some tests that require internal-only packages to run) is:
commit 3c66be240f1ee1f1b5f03bed79eb0d9f8c08965a

Cmd.Wait(): handle EINTR return code from os.Process.Wait().
This is probably not actually the correct fix; most likely
os.Process.Wait() itself should be fixed to retry on EINTR so that it
never leaks out of that function. But if we're going to patch a
particular module, it's safer to patch a higher-level one like os/exec
rather than the os module itself.
