build_abi: update the ABI whitelist whenever we refresh the representation
The script `extract_symbols` extracts the symbols that are actually
needed by modules that we build along with the vmlinux. As they change,
we also need to update the whitelist (additive) to add new symbols that
we want to keep stable from now on (as they are potentially used).
Do this whenever we use --update of build_abi.sh
