chore(execution-environment): Specify image-classification canister W…

…ASM as a Bazel dependency (#3355)

This PR makes image-classification.wasm.gz (currently, a checked-in
binary artifact) a Bazel dependency, so multiple tests that require
either specifically this canister, or just a very large WASM, can share
it. This change required adjusting
`//rs/execution_environment:execution_environment_misc_integration_tests/smoke`.
