selftests/bpf: Add a test for objects stuck in free_by_rcu_ttracegrafted
Delete all elements of BPF_F_NO_PREALLOC hash map in one batch. The first free_bulk() starts RCU tasks trace GP and the rest of the elements are freed while it's in flight. Wait for call_rcu_ttrace_in_progress to clear in bpf_mem_cache of every cpu and check that free_by_rcu_ttrace and waiting_for_gp_ttrace lists are empty.

+ help
+ Run the PSCI checker during startup. This checks that hotplug and
+ suspend operations work correctly when using PSCI.
+
+ The torture tests may interfere with the PSCI checker by turning CPUs
+ on and off through hotplug, so for now torture tests and PSCI checker
+ are mutually exclusive.
