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.
