feat(lvm): always include all drivers that LVM can use

This patch adds all the kernel modules that might be needed by LVM, to avoid
having to rebuild the initrd in hostonly mode after a dynamic change that
requires new drivers to boot.

For example, LVM allows to dynamically convert a linear logical volume to a
RAID-1 type (`lvconvert --type raid1 vg/lv`), which, in hostonly mode, will
require the user to manually rebuild the initrd again to include the new RAID
drivers in use, otherwise the system will fail to boot.
