Subject: [PATCH] libpcap: add rpcapd as package (#7631)

This enables building of rpcapd and adds it as a package.

It is a daemon that allows remote packet capturing from another machine.
E.g. Wireshark can talk to it using the Remote Capture Protocol (RPCAP).
https://www.tcpdump.org/manpages/rpcapd.8.html

Compile and run tested: OpenWrt SNAPSHOT r17190-2801fe6132 on x86/64
