Our documentation claims that the DEFCONFIG make variable, used for
targets such as savedefconfig, defaults to 'defconfig'.
With the update to kconfig 5.13 we lost this default, so bring it back.
Fixes: 53ea1d44f0 ("util/kconfig: Uprev to Linux 5.13's kconfig")
Resolves: https://ticket.coreboot.org/issues/317
