* fix: allow extracts on zip files to fail

Changes in intel#1181 to check return codes made it so failed extractions
caused cve-bin-tool to halt rather than log an error. This was
particularly a problem for .exe files, which we try to extract as
zipfiles in case they are self-extracting exectables.
