ci: skip Docker Hub login step on fork PRs (#3417)

On fork PRs, `secrets.DOCKERHUB_LEROBOT_*` expand to empty strings,
which fails `docker/login-action@v3` with `Error: Username and
password required` before any of the actual build/eval work runs.

Gate the login step on the env-var expansion of the username so the
step is skipped (not failed) when secrets are absent. On the main
repo + maintainer-approved fork runs (`pull_request_review` path),
the secrets resolve normally, the step runs, and image pulls get
the authenticated Docker Hub rate limit.

Scope: only `benchmark_tests.yml`, the lone benchmark workflow that
triggers on `pull_request` from forks. `full_tests.yml` and
`latest_deps_tests.yml` run under `pull_request_review` / schedule /
workflow_dispatch, where secrets are already guaranteed.

Context: surfaced on #3416 where an external contributor's PR failed
at the login step before any test could run.
