[PATCH 2/4] docs: admin-guide: fix stress-ng command examples

[Cheng-Han Wu]

The workload tracing guide includes stress-ng command examples with a
stray "command." word at the end. This makes the examples invalid if they
are copied and run directly.

Remove the stray word from the stress-ng example. Also use "--" in the
perf record example to clearly separate perf record options from the
workload command being recorded.
