Hanno Becker 623e7b4422 ssl_client2: Skip CA setup if ca_path or ca_file argument "none"
This allows to test PSK-based ciphersuites via ssl_client2 in builds
which have MBEDTLS_X509_CRT_PARSE_C enabled but both MBEDTLS_FS_IO and
MBEDTLS_CERTS_C disabled.

A similar change is applied to the `crt_file` and `key_file` arguments.
