ufp: add a device fingerprinting daemon

Add a daemon that can fingerprint devices based on DHCP, MDNS and WiFi
signatures.

Sample output looks like the following.
{
	"04:99:b9:XX:YY:ZZ": {
		"device": "HomePod mini",
		"vendor": "Apple",
		"class": "speaker",
		"device_name": "Kitchen"
	},
		"c4:65:16:XX:YY:ZZ": {
		"vendor": "HP",
		"device": "OfficeJet Pro 9010 series",
		"class": "Printer"
	}
}
