ufw requirements not met by goldfish config

I ran the security image tests under the x86 emulator and discovered that the kernel configuration is not sufficient to use ufw. Granted, using ufw under the x86 touch emulator is itself a bit of a corner case, however, there shouldn't be a reason to exclude these netfilter options and if the emulator is going to become a touch image smoke test target (eg, http://ci.ubuntu.com/smokeng/utopic/), then this will have to be fixed for the tests to pass.

Steps to reproduce:
1. create and start the emulator (use --revision=NN with 'create' when using already downloaded images in $HOME/emulator ubuntu-emulator). Eg:

$ sudo XDG_CACHE_HOME=$HOME/emulator ubuntu-emulator create --channel=ubuntu-touch/utopic-proposed --arch=i386 test_x86
$ ubuntu-emulator run --scale=0.5 test_x86

2. run the check-requirements script:
$ adb shell /usr/share/ufw/check-requirements -f | grep FAIL

This easiest thing to do would be to use the same netfilter options as on generic or mako.
