jit-trust: adapt for esp-idf pre v3 mbedtls 

Ensure we still work with mbedtls_ssl_conf_verify() as well as
mbedtls_ssl_set_verify() if that's what we have got.

Make sure mbedtls tls validation is noisy and fast.

Disable Xenial + mbedtls in sai, it fails but not when the same
tests are run from the commandline.  Very few people will be
using Xenial (2016 Ubuntu release) with mbedtls.
