    _stackmanager: Only try to write /proc/sys/net/core/xfrm_acq_expires when needed
    
    This supresses a few warnings that can pop up (eg on EC2 docker containers)
    
    Also do not test for writable access, as that test itself seems to generate
    a writeable error anyway. So just write and let the error speak for itself.
    
    if the value set is different from the value, warn the user/syslog:
    
    changing /proc/sys/net/core/xfrm_acq_expires from 30 to 15
