nixos-generate-config: add support for bcache
Add "bcache" to boot.initrd.availableKernelModules if a bcache device is detected. This fixes a problem I've had one too many times: I install NixOS and forget to add "bcache", resulting in an unbootable machine (until fixed with Live CD). Now NixOS will do it for me.
