[PATCH 2/3] trace2: trim whitespace in start message in perf target format

[Jeff Hostetler via GitGitGadget]

From: Jeff Hostetler <jeffh...@microsoft.com>

Trim leading/trailing whitespace from the command line
printed in the "start" message in the perf target format.

We use `sq_quote_argv_pretty()` to format the message
and it adds a leading space to the output.  Trim that.
