Dear Guix,

I'd like to update Virtuoso OSE to the latest release (see attached patch).

Other than the version number and checksum bump I noticed that some JAR files made it in the build
output.  I tried removing them from the source tarball using a snippet, but then one needs to
include a patch for various Makefile.am files and run the autogen.sh script.  I thought this was
simpler and clearer on what's actually achieved.

Kind regards,
Roel Janssen
