Trim Packages (#96)

Closes #81 

* Trim Packages

Kernel support for USB has been moved to modules
libpcap and tcpdump have been moved to modules
libnetsnmp and snmpd have been moved to modules
IPv6 has been removed from the kernel
IPv6 support has been removed from busybox network utils as well.
(no more funny DNS responses in nslookup!)

They are no longer needed

* Changed patch name and number and updated series file
