cc: Re-enable tile eviction iterator test with occlusion.

This patch re-enables a patch that was timing out on windows. This
code has changed significantly since it was disabled, and it's worth
seeing if the problem went away.

NOTE TO SHERIFFS
================

In case of a cc_unittest timeout (one of TileManager tests with
occlusion), please revert this. I'll monitor how it goes, but I might
miss it in the build.
