netfilter: ebtables: also count base chain policies
commit 3b48300d5cc7c7bed63fddb006c4046549ed4aec upstream.
ebtables doesn't include the base chain policies in the rule count,
so we need to add them manually when we call into the x_tables core
to allocate space for the comapt offset table.
This lead syzbot to trigger:
