[libsoup] Only set "ssl-ca-file" in examples/get if provided on the commandline

commit ad434349d72831857918f590a2e76010cf086962

    Only set "ssl-ca-file" in examples/get if provided on the commandline
    
    Otherwise the default system CA database is not going to be used if
    nothing is given on the commandline, and certificate verification fails.
