380390c4b6 misc: relax fatal errors in ssh_analyze_banner 
Relax the cases where `ssh_analyze_banner` fails to extract a
major and minor version from banners which appear like OpenSSH
banners.

Update the tests to demonstrate that now a banner as might be
sent by `ssh-keyscan(1)` ("SSH-2.0-OpenSSH-keyscan") no longer
returns failure.

It is possible that we get unrelated packets while waiting for
termination, thus waiting indefinitely. As a workaround we have to
