t/perf/p7519: speed up test on Windows
Change p7519 to use `test_seq` and `xargs` rather than a `for` loop to touch thousands of files. This takes minutes off of test runs on Windows because of process creation overhead. Signed-off-by: Jeff Hostetler <jeffhost@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
