test_dnssec: re-add named-pkcs11 workarounds
DNSSEC tests starrted to fail again, probably due to a bug in
some underlaying component.
This reverts commit 8bc677512296a7e94c29edd0c1a96aa7273f352a
and makes the xfail test check less strict - it will no longer
mark the test suite red if it passes.
Run DNSSEC tests on PR-CI
