support/scripts/pkg-stats: add unsure_cves to cve_total calculation

When I initially made the CVE cells collapsible, I neglected to
count the unsure CVEs. This patch adds unsure CVEs to the cell collapsing
calcualation to ensure that cells with lots of unsure CVEs actually get collapsed.

This patch also removes the "+ 1" from the cve_total calculation,
which fixes the cve_total being off-by-one.
I'm not sure *why* I did that in the first place.
