Segment entries hash only their data, so compare_artifacts reported a
segment that moved to another load address with the same bytes as
unchanged; only the image itself changed. Compare each segment's
load_addr and data_len as its declaration, as Node SEA and PyInstaller
members are compared, and count a changed declaration as a metadata
change, also when content is unavailable.
Header offsets are layout and the classification is derived, so neither
is compared.
