mkdumprd: do not lookup in by-uuid dirs for raw device's persistent name

Browse Source 
raw devices are not mounted and also does not need to contain any
filesystem. So they may have UUIDs(when formatted) and may not have UUIDs
when raw. Therefore, do not look for persistent names by-uuid for raw
devices.
