Subject: [PATCH] nixos/bcache: add services.udev.packages = [ bcache-tools ]

Adds /dev/disk/by-{id,label}/* symlinks for bcache device nodes, in the
final rootfs.

Symlinks will only be created for bcache devices that contain
filesystems. So if you have a blank bcache device or run LVM on top of
bcache you will not get this kind of symlink.
