autoboot: Rework CONFIG_AUTOBOOT_STOP_STR_* usage

In order to not define a CONFIG value when the
CONFIG_AUTOBOOT_STOP_STR_* functionality is not enabled, rework the
assignment of empty and unused (as the code will be discarded under if
0, in the end) values to be AUTOBOOT_STOP_STR_* instead of
CONFIG_AUTOBOOT_STOP_STR_*.
