tasks/lvm: add all tools from thin-provisioning-tools

Browse source 
This should barely increase the size of the initrd, because these are all symlinks.
With this, systems with dm-cache/lvmcache can also be booted, although the kernel modules for the relevant dm targets still need to be added to the initrd with boot.initrd.kernelModules.
