Subject: [PATCH] doc: Fix glossary entry for data checksums workers

The glossary entry for data checksums workers incorrectly stated that
they were auxiliary processes, but they are implementerd as background
workers.  Fix, and while there, simplify the entry by combining the
worker and launcher into a single glossary term.
