Arm backend: Fix off by one bug in print from arm_executor_runner (#14120)

The arm executor runner has ET_NUM_INFERENCES set to 1 by default but
the print after run stated it has done 2 runs.

The for loop doing the execution started on 1 and checked with <=
causing the num_inferences to tick over by one.
