clr-boot-manager: add support for non-lvm root encryption

Browse Source 
cbm_get_luks_uuid get the uuid of the decrypted root partition when this
is in a LVM partition this mean looking for the device information here:
/sys/block/dm-1/slaves/dm-0/slaves/sdb1/dev
without LVM the path would be this:
/sys/block/dm-1/slaves/sdb1/dev
