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.

+	  ACRN Hypervisor Service Module (HSM) is a kernel module which
+	  communicates with ACRN userspace through ioctls and talks to
+	  the ACRN Hypervisor through hypercalls. HSM will only run in
+	  a privileged management VM, called Service VM, to manage User
+	  VMs and do I/O emulation. Not required for simply running
+	  under ACRN as a User VM.
+
+	  To compile as a module, choose M, the module will be called
+	  acrn. If unsure, say N.
