[PATCH 6/9] pynfs: add makefile target to show test results

[Scott Mayhew <smayhew@redhat.com>]

Add 'pynfs-show-results' makefile target to show test results.

Under the hood, it more or less just does 'find ... | xargs cat'.

It shows the json results files for the most recent kernel run.  You can
show the results for a differnt kernel by overriding the LAST_KERNEL
variable, e.g.

$ LAST_KERNEL=6.13.4-300.fc41.x86_64 make pynfs-show-results
