[Crash-utility] [PATCH v2] list: Enable LIST_HEAD_FORMAT for -r option
Previously, if LIST_HEAD_FORMAT was not set, `list -r` will traverse the
list in order, that doesn't obey the -r(reverse) semantics.
Per the code, -r(LIST_HEAD_REVERSE) only work with LIST_HEAD_FORMAT and
'-r' usage also says that "For a list linked with list_head
structures",
so it's reasonable to enable LIST_HEAD_FORMAT for it.
