[v9_11] Add respdiff job with third-party recursors

Merged Michal Nowak requested to merge mnowak/respdiff-add-third-party-server-support-v9_11 into v9_11

The order of directories with reference and test BIND 9 are now reversed for respdiff.sh.

Drop unnecessary dependency on the tarball-create job.

The data.mdb file has more than 10 GB and makes artifact download take an unnecessarily long time.

(cherry picked from commit 2ececf2c)
