RFR (S): JDK-8025921 Make LOG=debug output more readable

[Erik Joelsson]

Unfortunately, the patch failed when I tried submitting it. Usage of the 
ListPathsSafely macro in SetupArchive is a bit different and needs to be 
adjusted. Here is a webrev that I have verified to work:

I also reduced duplication and slightly changed the debug message. At 
least to me, assuming word 2 of $3 to be a filename feels a bit of a 
hack, even if it's usually the case.
