fstests: add makefile target to show test results

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 xunit_result.txt file 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 xml output files:
$ PATTERN="-name \"*.xml\"" make fstests-show-results

or to see the xunit_results.txt 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 \"*.bad\"" make fstests-show-results

Finally, note that if you override the PATTERN variable, then the output
will also include the filename... otherwise it the output will not
include the filename.  The reason I did it this way for this workflow
specifically is so that Luis can use 'make fstests-show-results' in his
github workflow and he should get exactly the same output as he does
today.
