scftorture: Count single_rpc offline failures in statistics outputgrafted

scf_torture_stats_print() aggregates each invoker thread's counters
into a local scf_statistics structure before printing, but the
n_single_rpc_ofl field is missing from the aggregation loop.  As a
result, the "single_rpc_ofl" value printed in the statistics line is
always zero, even when smp_call_function_single() invocations for the
RPC test have failed due to offline CPUs and been counted by the
invoker threads.

Add the missing accumulation so that the printed value reflects the
actual counts.

+	  Landlock is a sandboxing mechanism that enables processes to restrict
+	  themselves (and their future children) by gradually enforcing
+	  tailored access control policies.  A Landlock security policy is a
+	  set of access rights (e.g. open a file in read-only, make a
+	  directory, etc.) tied to a file hierarchy.  Such policy can be
+	  configured and enforced by any processes for themselves using the
+	  dedicated system calls: landlock_create_ruleset(),
+	  landlock_add_rule(), and landlock_restrict_self().
+
+	  See Documentation/userspace-api/landlock.rst for further information.
+
+	  If you are unsure how to answer this question, answer N.  Otherwise,
+	  you should also prepend "landlock," to the content of CONFIG_LSM to
+	  enable Landlock at boot time.
