crypto-client test: ensure that client/server are linked against proper MbedTLS libraries

Ensure that both server and client can call mbedtls_version_get_string_full()
to verify that they are linked against proper libraries.

Note: each side (client/server) performs the call against its own
MbedTLS library. There is no IPC communication involved in this
test. Client/server communication will come later.
