fix(ndt7): force our bundled CA pool (#700)

Browse Source 
This change should prevent old clients (e.g., Android 6) from
failing to perform a ndt7 experiment because their internal CA
bundle is now too old.

Reference issue: https://github.com/ooni/probe/issues/2031

While there, run `go mod tidy` to fix a minor inconsistence in
the current `go.mod` file.

This diff WILL require a backport to release/3.14.
