doc: netlink: Update tc spec with missing definitions

The tc spec referenced tc-u32-mark and tc-act-police-attrs but did not
define them. The missing definitions were discovered when building the
docs with generated hyperlinks because the hyperlink target labels were
missing.

Add definitions for tc-u32-mark and tc-act-police-attrs.
