    util.c: check if return value from ttyname_r is > 0 instead of != 0
    
    We must return a negative error code from getttyname_malloc but
    that would not be the case if ttyname_r returned a negative value.
    
    ttyname_r should only return EBADF, ENOTTY, or ERANGE so it should
    be safe to change.
