fix: include VXLAN persistent networks in cleanup resource dispatch

cleanupPersistentnNetworkResources() only sent CleanupPersistentNetworkResourceCommand
for networks whose broadcast URI scheme is vlan, so vxlan:// persistent networks
leaked bridges and VXLAN interfaces on hosts that never ran a VM on them.
setupPersistentNetwork() creates resources for all persistent networks with no
scheme filter, so the removal path must accept both Vlan and Vxlan schemes.

Fixes #13966.
