[PATCH 5/9] fstests: add makefile target to show test results

[Scott Mayhew <smayhew@redhat.com>]

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

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

By default, the result.xml files will be shown for the most recent
kernel run.  You can show the results for a different kernel by
overriding the LAST_KERNEL variable, e.g.
$ LAST_KERNEL=6.13.4-300.fc41.x86_64 make fstests-show-results

You can change the files being shown by overriding the PATTERN variable.
For example, to just see the summary:
$ PATTERN="\( -name xunit_results.txt \)" make fstests-show-results

or to see the summary and the bad results:
$ PATTERN="\( -name xunit_results.txt -o -name \"*.bad\" \)" make fstests-show-results

or you can do any combination thereof, e.g.
$ LAST_KERNEL=6.13.4-300.fc41.x86_64 PATTERN="\( -name xunit_results.txt \)" make fstests-show-results
