netfilter: bridge: build br_nf_core only if required
Eric reports build failure with
CONFIG_BRIDGE_NETFILTER=n
We insist to build br_nf_core.o unconditionally, but we must only do so
if br_netfilter was enabled, else it fails to build due to
functions being defined to empty stubs (and some structure members
being defined out).
Also, BRIDGE_NETFILTER=y|m makes no sense when BRIDGE=n.
Fixes: 34666d467 (netfilter: bridge: move br_netfilter out of the core)
