The 'capability_filters' allows admins to globally disable some qemu capabilities via the config file. Until now it was applied only directly when starting the VM, but that is too late as the capability is still present when e.g. the post-parse code is picking defaults. Rework the code so that 'capability_filters' is applied directly after probing qemu so all existing capabilities will lack the filtered out ones.
