This is something caught in UNH FreeBSD env.
For some reason [1], the pcap/bpf.h header started to define _BPF_H_.
It happens that the bpf_impl.h internal DPDK header uses this define as
an internal guard.
This triggers a build failure in bpf_convert.c which can't find
RTE_BPF_LOG macro.
Fix the include guard to use the filename and remove _.
