Subject: [PATCH] utils.py: Fix logic for determining word size

Currently list_eth_names() checks architecture width to determine
offset for interface array name lookup. This gets broken for ppc64le
architecture. Changing this logic to use 'sys.maxsize'. This issue
got exposed with 'targetcli' command.
