[Ulf Jordan]

Hello!

The attached patch fixes bold attribute and positioning in libpayload 
serial output. Compile tested against r3478 (latest non-broken 
libpayload+coreinfo) and runtime tested with coreinfo+coreboot-v3 in QEMU 
(serial output in xterm).

upper left corner is (0,0) in curses, but (1,1) on the vt100.
