network: Fix security groups for CentOS (#2590)
On RHEL/CentOS/Fedora the bridge related sysctl rules are enabled
in kernel by default but can only be disabled. Enabling those keys
will fail, causing iptables/ebtables tables to not be created
and fails SG on CentOS.

This also fixes an integration test case, which assumes first few
tests complete within 3 minutes. In nested env the value may be large,
this increases the value to 20 minutes.
