rust: workqueue: replace deprecated system_wq with system_{percpu,dfl}_wq
system_wq is deprecated and triggers a runtime warning:
[ 0.857414] workqueue: work func ...WorkItemPointerKy0_E3runB7_ enqueued on deprecated workqueue. Use system_{percpu|dfl}_wq instead.
Replace system() with system_percpu() and system_dfl(), to match the
previous behavior of the deprecated system() and convert doc examples
and tests to system_dfl().
system_unbound_wq is deprecated in the same way, in favor of
system_dfl_wq. Since system_unbound() has no users, just remove it as
well.
Fixes: 64d8eae3f895 ("workqueue: Add warnings and fallback if system_{unbound}_wq is used")
