Support /usr/sbin paths for aircrack-ng on Debian and add hcxtools

- Add get_tool_path() to check /usr/sbin and /sbin for tools
- Update wifi.py to use full paths for airmon-ng, airodump-ng, aireplay-ng, aircrack-ng
- Add hcxdumptool and hcxtools to setup.sh for Debian and macOS
- Update check_cmd() in setup.sh to also check /usr/sbin and /sbin
