Small fix to recovery code

This appears to succeed in doing a two way certificate check.
Example command lines :

acer: {12} ./ssl_client2 server_name=waskot server_port=4433 ca_file=/home/danny/src/esp-idf/espalarm/build/main/my-ca.crt key_file=/home/danny/src/esp-idf/espalarm/build/main/client.key crt_file=/home/danny/src/esp-idf/espalarm/build/main/client.crt auth_mode=required
acer: {4} curl -vvv --cacert /home/danny/src/esp-idf/espalarm/build/main/my-ca.crt --key /home/danny/src/esp-idf/espalarm/build/main/client.key --cert /home/danny/src/esp-idf/espalarm/build/main/client.crt https://waskot:4433

This gets recognized by the server, and it prints info from the certificate.

Need 2048 bits to work with mbed, and add some dependency rules

Make this somewhat less verbose..
