cbfstool: provide printk() to cbfstool code

For shared compilation units between coreboot proper
and cbfstool that means one needs to provide printk
logging. Therefore, provide printk() at <console/console.h>
to mimic coreboot's environment.

BUG=chrome-os-partner:44827
BRANCH=None
TEST=Built cbfstool with code that includes and uses
     <console/console.h>.
