  CONFIG options for (ipip, sit) should not be built-in to the KVM

Bug description:
  CONFIG_NET_IPIP and CONFIG_IPV6_SIT are set to =y in the -kvm kernels.

  This means that they are always present in the kernel, and the virtual
  devices they created (tunl0 and sit0) are always present, even when
  not configured and not needed.

  This is causing some issues for clouds that use the -kvm flavour, and
  there is no good reason for those configuration options to be =y
  anyway.

  So they should be converted to =m instead.

  [Regression potential]
   - The only possible regression I can think of by compiling these as modules is the possibility that someone's boot setup somehow depended on IP tunneling. Such issues would need to be worked out by some initramfs means, etc. 
   - After this change, the modules (ipip.ko, sit.ko) are present in linux-modules.
   - General consensus was that these options should have been =m all along.
