Update openapi bazel build to support vendored build

This is one part (see #54335) of enabling vendoring projects like federation to generate openapi code for k8s.io/kubernetes.

edit: These changes are necessary for a project to correctly generate ``vendor/k8s.io/kubernetes/pkg/generated/openapi/zz_generated.openapi.go`` for vendored ``k8s.io/kubernetes``.  Without the changes, the vendored output location for ``zz_generated.openapi.go`` would be ``k8s.io/kubernetes`` instead of ``vendor/k8s.io/kubernetes`` and the input files would similarly be from ``k8s.io/kubernetes`` instead of ``k8s.io/myproject``.
