[PATCH 3/3] submodule init: redirect stdout to stderr

From
Stefan Beller <sbeller@google.com>

Reroute the output of stdout to stderr as it is just informative messages, not to be consumed by machines.

This should not regress any scripts that try to parse the current output, as the output is already internationalized and therefore unstable.

We want to init submodules from the helper for `submodule update` in a later patch and the stdout output of said helper is consumed by the parts of `submodule update` which are still written in shell. So we have to be careful which messages are on stdout.
