bundle1: fix bundle1-denied reporting for push over ssh

Changeset b288fb2724bf introduced a config option to have the server deny push
using bundle1. The original protocol has not really be design to allow such kind
of error reporting so some hack was used. It turned the hack only works on HTTP
and that ssh wire peer hangs forever when the same hack is used. After further
digging, there is no way to report the error in a unified way. Using 'ooberror'
freeze ssh and raising 'Abort' makes HTTP return a HTTP500 without further
details. So with sadness we implement a version that dispatch according to the
protocol used.

We also add a test for pushing over ssh to make sure we won't regress in the
future. That test show that the hint is missing, this is another bug fixed in
the next changeset.
