fix(ci): clean stale legacy tracked dirs before submodule init

After the monorepo split, the old eafw_* directories remain on disk on
the staging server even after git reset --hard (the directories aren't
removed because they were tracked content, not files). git submodule
update --init then fails with 'destination path already exists and is
not an empty directory'.

Remove any eafw_* directory that doesn't already contain its own .git
reference before running the submodule init. Idempotent — once the
cleanup runs once and the submodules are properly checked out, the
condition (! -e $sub/.git) is false and the rm is skipped.
