From 32da4e319bac527b1ef70f392b5c93d9d4d5ceb4 Mon Sep 17 00:00:00 2001
From: Leah Rowe <leah@libreboot.org>
Date: Fri, 29 Sep 2023 17:23:47 +0100
Subject: merge include/fetch.sh, blobutil.sh, defconfig.sh

They are only ever used by script/update/blobs/*, so
put them all in blobutil.sh. This cuts down on the
number of scripts in lbmk.
