This is useful for checking the CRC-32 checksum of files used by the
loader. It outputs the checksum in signed decimal format, which is the
format used in the file name suffixes in the loader (e.g.
unpackclass_-1911426584.pack).

These are useful for manipulating the files used by the loader, some of
which are compressed with DEFLATE or headerless gzip.

I'm very keen on being able to use the jdk.jartool module (which is only
available in JDK11 onwards) as it allows us to avoid shelling out to
jarsigner entirely.
11 is the current LTS release and is already widespread in Linux
distributions, so I think it's reasonable to require it.
This commit removes the jsobject module. We might need to re-add it in
the future (if jdk.jsobject is removed from the JDK). However, it was
only necessary in 8 because modern versions of 8 tended to be
distributed without plugin.jar. JDK11 is distributed with the
jdk.jsobject module.
