Bump pcap to address TODO comment in split tunnel implementation

[MarkusPettersson98]

This PR replaces some auto-generated libpcap bindings for macOS with recently (WIP) released APIs in the pcap crate. By using Capture::want_pktap we can get rid of 3 uses of unsafe in the implementation of split tunneling on macOS, while removing some no-longer needed bindings.

    // libpcap will do the heavy lifting for us if we simply request a "pktap" device.

    // TODO: upstream exposure of a raw handle to pcap_t on Capture<Inactive>

I think we don't need the raw pointer, so we can probably remove this TODO comment as well.
