libpayload: Add an option to skip console initialization on startup.

A payload may want to decide whether it uses certain input/output consoles,
or that it wants support for outputing to a particular device but not to use
that device as a console. This change adds a config option which skips the
call to console_init in start_main.

Normally, libpayload will initialize console input/output on startup
before the payload itself gets control. This option disables that
behavior and leaves console initialization up to the payload.
