tools/syz-check: improve matching netlink attributes

1. Match policies that has a _suffix in our descriptions
(we frequently do this to improve precision or avoid dup names).
2. Rename policies in descriptions to match kernel names.
3. Match policy if there are several such names in kernel.
4. Recognize policies with helper sub-policies.

Update #590
