netfilter: x_tables: validate all offsets and sizes in a rule
commit 13631bfc604161a9d69cd68991dff8603edd66f9 upstream.
Validate that all matches (if any) add up to the beginning of
the target and that each match covers at least the base structure size.
The compat path should be able to safely re-use the function
as the structures only differ in alignment; added a
BUILD_BUG_ON just in case we have an arch that adds padding as well.
