matchbox-flatcar: disable all LVM mappings

Since the disks may or not be not empty, any detected LVM partitions may automatically be activated on bootup. This can disrupt the installation and we need to disable them first. This was done for all "vg" prefixes but we can do it for any volume names. Any non-LVM entries are ignored with a small error log output. See flatcar/Flatcar#332
