This script was broken by the change to default archives for linking.
This is due to objcopy specifically disallowing copying of thin
archives. To fix this and re-support external users of this script,
switch to using the same logic the u-boot-initial-env make target uses
to dump the section from the object file.

Fixes: 958f2e57ef ("build: use thin archives instead of incremental linking")
