The meson build was missing the define to enable pcap port support if
libpcap (development) package was found on the build platform. Rather than
duplicating the checks for libpcap found in the pcap net PMD build file, we
can move the checks to the top-level config directory and reference the
RTE_PCAP_PORT setting elsewhere in the build.
