In BootZipCopyAction and AbstractJarWriter, SHA-1 hash is calculated for
stored entries requiring unpack and set as entry comment. However, the
hash isn't used anywhere, just the marker prefix 'UNPACK:' is checked.
This commit removes the unnecessary SHA-1 hash calculation which reads
the file completely in memory, potentially three times in extreme cases.
Now the comment is simply set to 'UNPACK:' without any hash, improving
performance.
