Skip L2 FIB flush tests

These tests attempt to flush static entries from a bridge-domain that has no aging configured. for both reasons it will fail.
The fact thtat they occationally pass is due to the fact that the assert_nothing_cpatured does not actually capture packets, so it misses the fact that there are some.
