tests/krb5/s4u_tests.py: add test_constrained_delegation_with_enc_auth_data_[no_]subkey()

This demonstrates that we use the correct key for EncAuthorizationData
together with constrained delegation.

The actual fix for the problem is already in place via
commit 75ec66c729faad60fa18b9504ba4053b3e2f47bc
third_party/heimdal: Import lorikeet-heimdal-202306091507 (commit 7d8afc9d7e3d309ddccc2aea6405a8ca6280f6de)
