Richard W.M. Jones e43ca19129 daemon: inspect: Resolve Ubuntu 22+ /dev/disk/by-id/dm-uuid-LVM-... in fstab 
Linux + LVM supports device names like /dev/disk/by-id/dm-uuid-LVM-
followed by two concatenated UUIDs, firstly for the volume group and
secondly for the logical volume.  We can reverse those to get the
device name (/dev/VG/LV).

fstab entries look like:

  # / was on /dev/vg0/lv-0 during curtin installation
  /dev/disk/by-id/dm-uuid-LVM-OzFWT6NHkstr1hcmrWRRMDGPn9xdZj1YOOycQ533186x288FdU6UubU3OlnWJz6D / ext4 defaults 0 1
  # /usr was on /dev/vg0/lv-1 during curtin installation
  /dev/disk/by-id/dm-uuid-LVM-OzFWT6NHkstr1hcmrWRRMDGPn9xdZj1YZu53m4ZssZ8Jeb3I14RAJwIj5YlHIb9P /usr ext4 defaults 0 1

The upshot of this fix is that we are now able to correctly inspect
and run virt-v2v on Ubuntu 22+ guests with split /usr.  In particular,
we correctly map /etc/fstab entries like the above to LV device names,
which means that /usr merging now works correctly.
