keepalived: Fix ordering of config sections

keepalived seems to be rather particular about which config parameters
come before others.

When defining a virtual IP address, keepalived will check to see if the
vrrp instance is associated with a valid interface. Previously, the
interface parameter was declared after the virtual IP address which
caused an error when keepalived tried to run this check. Keepalived
tries to fall back to checking if 'eth0' exists.

The fix is to re-order the config stanzas so that the interface
parameter comes before the virtual IP address definitions.
