netfilter: use IS_ENABLED(CONFIG_BRIDGE_NETFILTER)

In 34666d4 ("netfilter: bridge: move br_netfilter out of the core"), the bridge netfilter code has been modularized. Use IS_ENABLED instead of ifdef to cover the module case. Fixes: 34666d4 ("netfilter: bridge: move br_netfilter out of the core") Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
