[RFC net-next 2/7] selftests: openvswitch: Refactor actions parsing.

Until recently, the ovs-dpctl utility was used with a limited actions set
and didn't need to have support for multiple similar actions. However,
when adding support for tunnels, it will be important to support multiple
set() actions in a single flow. When printing these actions, the existing
code will be unable to print all of the sets - it will only print the
first.

Refactor this code to be easier to read and support multiple actions of the
same type in an action list.
