Ian Rogers d72e5cf3cf perf sched: Fix memory leaks in __cmd_record detected with -fsanitize=address ...

An array of strings is passed to cmd_record but not freed. As
cmd_record modifies the array, add another array as a copy that can be
mutated allowing the original array contents to all be freed.

Detected with -fsanitize=address.
