kernel/printk: use symbolic defines for console loglevels
... instead of naked numbers.
Stuff in sysrq.c used to set it to 8 which is supposed to mean above
default level so set it to DEBUG instead as we're terminating/killing all
tasks and we want to be verbose there.
There should be no functionality change resulting from this patch.
