snort: enable static daq

When start snort, it shows error and quit:

|         --== Initializing Snort ==--
| Initializing Output Plugins!
| ERROR: Can't find pcap DAQ!
| Fatal Error, Quitting..

Fix by enable static daq for snort and enable static build for daq. snort calls
command daq-modules-config which is from daq-native to get required daq static
libraries and library path. Add package daq-native and add patch for snort to
filter library path out to avoid host contamination issue.

Add daq-native's dependency libnet-native too. And daq-native also depends on
libpcap-native from layer oe-core.

+When enable static daq for snort, it calls to daq-modules-config to get link
+library and library path. Library path is useless for oe and cause host
+contamination issue. So filter it.
