On text-based systems the 'quiet' boot option will show printk levels
higher than CONSOLE_LOGLEVEL_QUIET.  The displaying of the Tux logo
during boot can cause some consoles to lose display data and as a result
confuse the end user.

Do not display the Tux logo on systems that are in 'quiet' boot.

v2: It helps to commit all my changes before sending them.  Remove extra
bracket.
v3: buildbot error fix: fbcon can be built as part of a module so export console_printk
v4: move console_printk change to separate patch, and drop logo cleanup
