--incompatible_remote_build_event_upload_respect_no_cache stops working when building an alias

[brentleyjones]

Description of the problem / feature request:

When using --incompatible_remote_build_event_upload_respect_no_cache and building an alias, bep-referenced items are uploaded to the remote cache even with --noremote_upload_local_results. When building the aliased target directly they are correctly excluded from upload.

Bugs: what's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

This will exclude blobs from upload:

$ git clone git@github.com:bazelbuild/rules_apple.git
$ cd rules_apple
$ env USE_BAZEL_VERSION=5.0.0rc3 bazelisk build --remote_cache=grpcs://remote.buildbuddy.io --bes_backend=grpcs://remote.buildbuddy.io --bes_results_url=https://app.buildbuddy.io/invocation/ --incompatible_remote_build_event_upload_respect_no_cache --noremote_upload_local_results //examples/iOS/StickersApp

While this won't:

$ echo '
alias(
    name = "through_alias",
    actual = "//examples/ios/StickersApp",
)' >> BUILD
$ env USE_BAZEL_VERSION=5.0.0rc3 bazelisk build --remote_cache=grpcs://remote.buildbuddy.io --bes_backend=grpcs://remote.buildbuddy.io --bes_results_url=https://app.buildbuddy.io/invocation/ --incompatible_remote_build_event_upload_respect_no_cache --noremote_upload_local_results //:through_alias

What operating system are you running Bazel on?

macOS 12.0.1

What's the output of bazel info release?

release 5.0 rc3
