Sync performance tests: add new sources in chrome_tests.gypi

Sync performance tests: add new sources in chrome_tests.gypi

The sync performance tests began timing out on the XP and Vista performance bots
shortly after tab sync tests were added.  This seems to be coincidental, because the
InProcessBrowserTest.Empty is timing out as well.

As an attempt to fix this issue, this patch takes all non test case source files that
are included in sync_integration_tests, and adds them to sync_performance_tests.

LGTM.

I'll try running this on my windows machine to confirm that it does the trick.
