app/dumpcap: allow help/version without primary process

Currently dumpcap tries to initialize dpdk before parsing command line
arguments, this makes it impossible to check version or help without
having the primary process running already.

build: cleanup libpcap dependent components

The RTE_PORT_PCAP variable is used to signal libpcap availability,
though its name seems to refer to pcap support in the port library.
Prefer a generic name and add explicit link dependencies where needed.

bpf: fix convert API when libpcap missing

rte_bpf_convert() implementation depends on libpcap.
Right now it is defined only when this library is installed and
RTE_PORT_PCAP is defined.
Fix that by providing for such case stub rte_bpf_convert()
implementation that will always return an error.
To draw user attention, if proper implementation is disabled,
warning will be thrown at meson configure stage.
Also move stub for another function (rte_bpf_elf_load) into
the same place (bpf_stub.c).

This is a new packet capture application to replace existing pdump.
The new application works like Wireshark dumpcap program and supports
the pdump API features.

It is not complete yet some features such as filtering are not implemented.
