[PATCH 4/9] ltp: add last-run directory and last-kernel.txt to the results

[Scott Mayhew <smayhew@redhat.com>]

Create the last-run directory and last-kernel.txt file in a manner
similar to the way the fstests workflow does it.

This will make it easier to get at the most recent test results for
reporting purposes.
