[SYCL][E2E] Pass freshly built OpenCL/L0 to e2e tests for in-tree configuration (#16742)

Our CI uses "standalone" configuration for running E2E tests, but
interactive development is (likely) mostly using in-tree configuration.
With this change we can enable more tests running by default in such
mode.
