ustream-ssl: mbedtls: fix ssl client verification

The ustream_ssl_update_own_cert() function should, like the name suggests, only
update the local ssl peer's own certificate and not the any of the CA's.

By overwriting the CA's certifcates when setting the own certificate, the code
broke SSL client verification.

This bug was only triggerd when:
 ustream_ssl_context_set_crt_file()
was called after
 ustream_ssl_context_add_ca_crt_file()
