ANDROID: sched: Export sched_domains_mutex for lockdep

Browse Source 
If CONFIG_LOCKDEP is enabled, export `sched_domains_mutex` as it is
indirectly accessed by the macro `for_each_domain()`. This allows
vendors to call the `for_each_domain()` macro with CONFIG_LOCKDEP
enabled via the GKI_BUILD_CONFIG_FRAGMENT.
