Justin Chadwell e206c585bb build: error on attests on non-multiplatform driver
On drivers that do not support multi-platform builds (the default
`docker` driver), we do not support building attestations (unless using
the containerd store).

We need to check this feature before attempting to build using
attestations.

Also adds a test to ensure that attestations can be pushed to registries
at all, and that it adequately fails on the docker driver.
