intg: Increase startup timeouts for secrets
    
    In cwrap environment, we start sssd_secrets ourself
    and not by systemd socket activation. Our approach is to wait a second in
    a loop till socket is available. However sometimes 1 second is not enough.
    Patch increases wait timeout from 1 second to 10 and it seems to be enough even
    when processes were executed with valgrind.
