Subject: [PATCH v2 4/6] lavf/tls_mbedtls: fix handling of certification
validation failures
We manually check the verification status after the handshake has completed
using mbedtls_ssl_get_verify_result(). However with VERIFY_REQUIRED
mbedtls_ssl_handshake() already returns an error, so this code is never reached.
Fix that by using VERIFY_OPTIONAL, which performs the verification but
does not abort the handshake.
