app/flow-perf: allow fixed values for actions

Sometime the user want to have fixed values of
encap/decap or header modify for all flows.

This will introduce the ability to choose from
fixed or dynamic values by setting the flag in
config.h

To use different value for each flow:
config.h: #define FIXED_VALUES 0

To use single value for all flows:
config.h: #define FIXED_VALUES 1
