openshift_node_dnsmasq - Remove strict-order option from dnsmasq

strict-order forces dnsmasq to iterate through nameservers in order. If one of
the nameservers is down this will slow things down while dnsmasq waits for a
timeout. Also, this option prevents dnsmasq from querying other nameservers if
the first one returns a negative result. While I think it's odd to have a
nameserver that returns negative results for a query that another returns
positive results for this does seem to fix the issue in testing.

Fixes Bug 1399577
