Fix Bazel --all_incompatible_changes

[qzmfranklin]

Some of the .bzl files use legacy starlark constructs that have been deprecated. The flag --all_incompatible_changes surfaces a few instances as such.

For example:

INFO: Invocation ID: d32772b6-fc44-4f2e-9ff4-26780574b35d
ERROR: /home/zhongming/git/LogiOcean/examples/jsonnet/BUILD:186:1: in jsonnet_to_json_test rule //examples/jsonnet:yaml_stream_test:

                ctx.file_action(output = ctx.outputs.executable, c...), ...)
Use ctx.actions.write instead of ctx.file_action. 
Use --incompatible_new_actions_api=false to temporarily disable this check.

Would like these incompatible changes to get cleaned up.

This should have been fixed a while ago.
