Added formulas for ntopng and ndpi

Dear all, please find enclosed the formulas for two open source tools ntop develops:
- nDPI: SDK for deep-packet inspection
- ntopng: web-based traffic monitoring application.

Thanks Luca Deri
/usr/local/Cellar/ntopng/1.2.1/bin/ntopng:
	/usr/lib/libpcap.A.dylib (compatibility version 1.0.0, current version 1.0.0)
	/usr/local/lib/libluajit-5.1.2.dylib (compatibility version 2.0.0, current version 2.0.3)
	/usr/local/lib/librrd.4.dylib (compatibility version 7.0.0, current version 7.1.0)
	/usr/local/lib/libjson-c.2.dylib (compatibility version 3.0.0, current version 3.1.0)
	/usr/local/opt/sqlite/lib/libsqlite3.0.dylib (compatibility version 9.0.0, current version 9.6.0)
	/usr/local/lib/libGeoIP.1.dylib (compatibility version 8.0.0, current version 8.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1197.1.1)
	/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 60.0.0)
	/usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 120.0.0)

so luajit, rrd, json, sqlite, libgeoip are the dynamic libraries I will put in the formula,
