Test t5516-fetch-push.sh has a test 'deny fetch unreachable SHA1,
allowtipsha1inwant=true' that checks stderr for a specific error
string from the remote. In some build environments the error sent
over the remote connection gets mingled with the error from the
die() statement. Since both signals are being output to the same
file descriptor (but from parent and child processes), the output
we are matching with grep gets split.

To reduce the risk of this failure, follow this process instead:

1. Write an error message to stderr.
2. Write an error message across the connection.
3. exit(1).

This reorders the events so the error is written entirely before
the client receives a message from the remote, removing the race
condition.
