Brian Goff bc9cb2c66a Add env var to disable default attestations
For certain cases we need to build with `--provenance=false`.
However not all build envs (especially in the OSS ethos) have the latest
buildx so just blanket setting `--provenance=false` will fail in these
cases.

Having an env var allows people to set the value without having to worry
about if the buildx version has the `--provenance` flag.
