[PATCH v2] selftests: openvswitch: Set value to nla flags.

[Adrian Moreno <amorenoz@xxxxxxxxxx>]

Netlink flags, although they don't have payload at the netlink level,
are represented as having "True" as value in pyroute2.

Without it, trying to add a flow with a flag-type action (e.g: pop_vlan)
fails with the following traceback:
