scripts/get_default_envs.sh: Update for thin archive support

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.
