nodeinfo: test more details

Make it obvious why we need Osier's patch in commit 10d9038b
to fix NUMA parsing of an AMD machine with two cores sharing
a socket id.

* tests/nodeinfotest.c (linuxTestCompareFiles): Enhance the test.
* tests/nodeinfodata/linux-nodeinfo-sysfs-test-*-output.txt: Update.
