build: improve pcap dependency handling pcap has historically shipped a custom pcap-config binary tool which does the job of pkg-config. It was never compatible with cross compilation. Meson uses it when using dependency(), which then means cross compilation fails. Set pcap-config to empty in the meson cross compilation files so that Meson will not use it, and add a fallback in case dependency() fails. libpcap 1.9.0 finally ships a pkg-config file so everything will work out of the box in the future.
