bsd_kbd: use newer LED_* consts
This driver is the only (known) one who's still using the old LED_* defines, like LED_CAP, LED_NUM, ... - these are just aliases to the newer ones, declared in xf86_OSlib.h.
In process of cleaning up old legacy, it would be nice to get rid of these, too. Since this driver seems to be only consumer left, it seems appropriate doing that little change and after then drop them from Xserver headers.
