netlink: add nla be16/32 types to minlen array

The message in question matches this policy:
[NFTA_TARGET_REV] = NLA_POLICY_MAX(NLA_BE32, 255),
but because NLA_BE32 size in minlen array is 0, the validation
code will read past the malformed (too small) attribute.
Note: Other attributes, e.g. BITFIELD32, SINT, UINT.. are also missing:
those likely should be added too.
