  LXD 4.2 broken on linux-kvm due to missing VLAN filtering

Bug description:
  [Description]

  Some VLAN options (BRIDGE_VLAN_FILTERING, and its dependencies
  VLAN_8021Q*) were in a different state in Focal/kvm compared to
  Focal/generic: LXD now depends on BRIDGE_VLAN_FILTERING and due to
  this discrepancy it fails to work on the Focal/kvm kernel: fix it by
  aligning the config with Focal/generic

  [Fix]

  Apply the attached config patch

  [Regression potential]

  Low, just some config changes already present in generic.

  ---
  This is another case of linux-kvm having unexplained differences compared to linux-generic in areas that aren't related to hardware drivers (see other bug we filed for missing nft).

  This time, CPC is reporting that LXD no longer works on linux-kvm as
  we now set vlan filtering on our bridges to prevent containers from
  escaping firewalling through custom vlan tags.

  This relies on CONFIG_BRIDGE_VLAN_FILTERING which is a built-in on the
  generic kernel but is apparently missing on linux-kvm (I don't have
  any system running that kernel to confirm its config, but the behavior
  certainly matches that).

  We need this fixed in focal and groovy.
