bridge: provide a cow_metrics method for fake_ops
Like in commit 0972ddb237 (provide cow_metrics() methods to blackhole
dst_ops), we must provide a cow_metrics for bridges fake_dst_ops as
well.
This fixes a regression coming from commits 62fa8a846d7d (net: Implement
read-only protection and COW'ing of metrics.) and 33eb9873a28 (bridge:
initialize fake_rtable metrics)
