console: USB: KBD: Fix incorrect autoboot timeout
Autoboot timeout defined by CONFIG_BOOTDELAY will not be accurate if
CONFIG_USB_KEYBOARD and CONFIG_SYS_USB_EVENT_POLL are defined in
configuration file and when tstc() function for checking key pressed
takes longer time than 10 ms (e.g., 50 ms) to finish.
