seat_output: add an output type for SSH banners. (NFC)

Browse Source 
The jump host system ought really to be treating SSH authentication
banners as a distinct thing from the standard-error session output, so
that the former can be presented to the user in the same way as the
auth banner for the main session.

This change converts the 'bool is_stderr' parameter of seat_output()
into an enumerated type with three values. For the moment, stderr and
banners are treated the same, but the plan is for that to change.
