    Fix sshd feature check
    
    OpenSSH server included in Fedora 18 raises a validation error when
    the tested AuthorizedKeysCommand/PubKeyAgent option is tested with
    an empty value. It requires a command with an absolute path to be
    passed. Due to this issue, sshd support is never configured on
    Fedora 18.
    
    Pass the real agent we will use later to the testing command to
    avoid this error.
