bootstd: Enable BOOTSTD_DEFAULTS by default

This is needed to enable the boot command used to start standard boot.
Enable it by default for boards which use BOOTSTD.

This brings in quite a few features, mostly in common with
DISTRO_DEFAULTS

Note: This actually only effects boards which don't have a custom
boot command, so there are no size increases from this patch.
