[PATCH kcsan 8/8] kcsan: Make strict mode imply interruptible watchers

[Paul E. McKenney]

From: Marco Elver <elver@xxxxxxxxxx>

If CONFIG_KCSAN_STRICT=y, select CONFIG_KCSAN_INTERRUPT_WATCHER as well.

With interruptible watchers, we'll also report same-CPU data races; if
we requested strict mode, we might as well show these, too.
