release: version 1.1.6 - Add local IP filtering and SLL support

Features:
- Add local_ips configuration option for filtering traffic to local machine
- Auto-detection of local IP addresses (excludes loopback 127.x.x.x, ::1)
- Support interface 'any' for capturing on all network interfaces
- Add Linux SLL (cooked capture) support for interface 'any'
- Generate BPF filter with 'dst host' for local IP filtering
- Add LinkType field to RawPacket for proper packet parsing

Testing:
- Add unit tests for local IP detection (detectLocalIPs, extractIP)
- Add unit tests for SLL packet parsing (IPv4 and IPv6)
- Update capture tests for new packetToRawPacket method

Configuration:
- Update config.yml.example with local_ips documentation
- Update RPM spec to version 1.1.6 with changelog
