[PATCH] openssh: allow root login when debug-tweaks is enabled

[Saul Wold <sgw@linux.intel.com>]

This allows root to login over ssh with an empty password just like
dropbear when the debug-tweaks are enabled, it's important to disable
debug-tweaks for a production system as this will leave open a security
hole!

Thanks to Marc for the settings.
