run_binary doesn't use target's RunEnvironmentInfo

If say `sh_binary` target has `env=` set, then running target directly uses env, but under run_binary `env=` values are getting lost.

Looks related to https://github.com/bazelbuild/bazel-skylib/issues/409 but `run_binary` isn't covered there

Inspect the run_binary rule and compare its handling of a sh_binary target's RunEnvironmentInfo with direct execution. Reproduce the case using a target with env= set, then verify that run_binary preserves those environment values; the related issue 409 provides additional context.
