Capture scripts for Coverity Scan analysis

coverity validation jobs: main, v9_18, and v9_16 (v9_11 is affected but not planned to be backported as it's close to EoL).

[STATUS] Running filesystem capture search...

The cov-build utility completed successfully.

This is blocked by this problem, the --fs-capture-search option breaks analysis: "Last Build Status: Failed - No further action needed.. Your build will be added back to the queue for analysis."

With Coverity Scan Support I managed to set "Secondary Language" to "PHP/Python/Ruby" for Coverity Scan projects, now Python scripts are being analyzed:

• main - bind-mnowak project - 2 CIDs
• v9_18 - bind-mnowak-v9_18 project - 2 CIDs
• v9_16 - bind-mnowak-v9_16 project - 6 CIDs

Closes #3138 (closed)
