perf: call clearcaches() in perfmanifest

The old code only partially cleared the caches. Now that we have a
comprehensive method for wiping all caches, let's call it.

This appears to introduce a marginal regression in `hg perfmanifest`
on mozilla-central. This is good because the new result is more
accurate since caches aren't being used.
