topology/cmake: skip all topologies when alsatplg < 1.2.5

Stop producing corrupted .tplg files when using `codec_consumer` (e.g.: sof-imx8mp-btsco-dual-8ch.tplg, sof-imx8ulp-9x9-btsco-16k.tplg, ...) Then we'll be able to finally search/replace "codec_master", see revert Signed-off-by: Marc Herbert <[email protected]>
