mod_c2s,mod_s2s: Advertise idle-seconds per XEP-0478
This is the time after liveness checks are performed via the respective
read-timeout event, which by default involves sending a space character
but could be overridden e.g. as is done by mod_smacks.
Only advertised, unsure what we would do with it.
