Disable OpenSSL's internal peer_name checking when verifyname is disabled.

[dd32]

Even with verify_peer disabled, OpensSSL will still perform peer_name checking, for example:

stream_socket_client(): Peer certificate CN=`dev.dd32.id.au' did not match expected CN=`test-vm'
stream_socket_client(): Failed to enable crypto
stream_socket_client(): unable to connect to ssl://test-vm:8443 (Unknown error)
