Remove VULN_THRESHLD relic

This fixes #2973.

There was a while back an extra headline when one or a defined other
number of vulnerabilities were checked. The extra headline was removed
n #2967 but some leftover code needed to be removed as well.

In the aforementioned previous PR it seems run_starttls_injection()
and run_rc4() were forgotten. This PR removes extra headlines in
those functions as well.
