Newer kernels have a write-only 'demote' file in the sysfs hugepages
directory.
The hugepagereport action uses a wildcard grep command to read all files
in these directories. Since the 'demote' file is write-only,
grep fails with a "Permission denied" error, causing the action and the
functional tests to fail.
This patch refactors the action to explicitly target only the relevant
metrics: 'nr_hugepages', 'free_hugepages', and 'surplus_hugepages'.
