selftests: forwarding: skip if kernel not support setting bridge fdb learning limit
[ Upstream commit 863ff546fb62a8fa75757a30794ab6ec6cc4bab7 ]
If the testing kernel doesn't support setting fdb_max_learned or show
fdb_n_learned, just skip it. Or we will get errors like
./bridge_fdb_learning_limit.sh: line 218: [: null: integer expression expected
./bridge_fdb_learning_limit.sh: line 225: [: null: integer expression expected
