rust: workqueue: Enable execution of doctests

Having the Rust doctests enabled these workqueue tests are built but not
executed as the final callers of the print_*() functions are missing.
Add them.

The result is

# rust_doctest_kernel_workqueue_rs_0.location: rust/kernel/workqueue.rs:35
rust_doctests_kernel: The value is: 42
ok 94 rust_doctest_kernel_workqueue_rs_0
# rust_doctest_kernel_workqueue_rs_3.location: rust/kernel/workqueue.rs:78
rust_doctests_kernel: The value is: 24
rust_doctests_kernel: The second value is: 42
ok 97 rust_doctest_kernel_workqueue_rs_3

Without this change the "The value ..." outputs are not there meaning
that this test code is not run.
