boot: driver chatter goes to the log; the console clears its margins

Browse source 
ACPI, DMI, SMP, xHCI, USB, I2C, NVMe, r8169 and ramdisk progress lines are
kinfo now: in dmesg and on a verbose boot, off the screen of a working
machine. Failures stay cprintf.

vt_repaint also paints the strip right of the last column and below the
last row, which kept the bottom of the X desktop after Ctrl+Alt+F-key.
