Copy container-sync-realms.conf in /etc/swift

fix sar reporting in the gate

the sar filter made an assumption of time display including an
AM/PM... which isn't true in all environments. Hence the blank
sysstat screen in the gate runs of late.

This fixes that, and displays the first line which includes header
version to make sure we are functioning.
