trafgen: Move checking of dynamic packet elements to header

Move has_dynamic_elems() to to trafgen_conf.h, rename it to
packet_dyn_has_elems() and use it to check whether dynamic
packet elements are present.

Also change the return type to bool and use || instead of + to
potentially make use of short-circuit evaluation.
