dissect-tool: hide device column if it's a short-lived loopback device

Browse source 
It's pointless showing info that isn#t going to survive the current
invocation, hence hide it.

The "partition number" column is more useful since it kinda shows the
same information, but without the device node name prefixed that is
local to the currentl invocation.
