A PE image's memory footprint might be larger than its file size due to uninitialized memory sections. Normally all PE headers should be parsed to check the actual required size, but the legacy EFI handover protocol is only used for x86 Linux bzImages, so we know only the last section will require extra memory. Use SizeOfImage from the PE header and if it is larger than the file size, allocate and zero extra memory before using it. Fixes https://github.com/systemd/systemd/issues/33816
