Fan Zhang b804f8fd1f examples/ip_pipeline: fix pcap file parsing 
This patch fixes the pcap file parsing in ip_pipeline. Originally, the
parser recognizes the pcap related entries regardless of the RTE_PORT_PCAP
macro definition status.

Fixes: fe5d046213 ("examples/ip_pipeline: add pcap file dump")
