gard: {list, show}: Fix the Type field in the output

The output of `gard list` has a field named "Type", however this
doesn't actually indicate the type of the record. Rather, it
shows the type of the path used to identify the hardware being
GARDed. This is of pretty dubious value considering the Physical
path seems to always be used when referring to GARDed hardware.
