Re: [PATCH v3 24/34] t/perf/p7519: speed up test using "test-tool touch"

From: Jeff Hostetler <redacted>

Change p7519 to use a single "test-tool touch" command to update
the mtime on a series of (thousands) files instead of invoking
thousands of commands to update a single file.

This is primarily for Windows where process creation is so
very slow and reduces the test run time by minutes.
