src/Kconfig: enable USE_BLOBS by default

To provide sane defaults for most of the user base, this patch switches
on the USE_BLOBS option by default. Since it only changes the default,
this behaviour can still be easily disabled.

With this abuild doesn't have to select USE_BLOBS any more, so what
abuild tests becomes the coreboot default again.
