metropolis: prevent printk console pollution

This implements two separate approaches to limit printk pollution of the
new tconsole:

 1. Sets the minimum printk level to EMERG. Everything lower than this
    level will not get blasted to tty0.
 2. Jut in case something does a spurious EMERG printk (or something
    just writes to tty0), we redraw the console. This makes it
    self-healing.
