hugepages: run hugepage check only on DPDK runmode and on Linux v3

[lukashino]

Follow-up of https://github.com/OISF/suricata/pull/10358

The previous implementation allowed FreeBSD to enter into the hugepage analysis. It then failed with an error message because hugepage/ NUMA node paths that are used in the codebase to retrieve info about the system are not the same as the structure in Linux.

Additionally, the messages were logged on an error level. It has been demoted to the info level because the whole hugepage analysis checkup is only for informational purposes and does not affect Suricata operation.

The hugepage analysis and the hugepage snapshots are now limited to only run in the DPDK runmode.

Changes: v3 changes:

• remove guards
• add a path check to determine hugepage validation
• add OS determination
• force-push change - adjusted the enum to follow the snake case format
