Unify the Linux kernel configurations Having N different copies of the NixOS kernel configuration is bad because these copies tend to diverge. For instance, our 3.10 config lacked some modules that were enabled in older configs, probably because the 3.10 config had been copied off an earlier version of some older kernel config. So now there is a single kernel config in common-config.nix. It has a few conditionals to deal with new/removed kernel options, but otherwise it's pretty straightforward. Also, a lot of cut&paste boilerplate between the kernel Nix expressions is gone (such as preConfigure).

linux_rpi: Specify defconfig in kernel expression In particular, now the mainline kernel can be built on the RPi 1 as well (so kernelBaseConfig should always be a mainline defconfig from now on). And RPi 2 users can now use linux_rpi without doing the `nixpkgs.config.platform = lib.systems.platforms.raspberrypi2;` dance.
