Subject: [PATCH v1] tools/rtla: Add missing --quiet option to timerlat hist

The --quiet option is available in all other rtla tools and documented
in the usage string, but was accidentally omitted from timerlat hist.

Add the missing --quiet option to timerlat hist for consistency and to
avoid confusion when silencing its output.
