Remove ash_unittests to see if it's affecting bot stability

Bot has been completely failing intermittently. ash_unittests
is the Win8-specific part that runs here, so temporarily remove
it to see if it's related to the back-and-forth to Metro

Add extensions_unittests target to main waterfall.

This puts extensions_unittests target in the major platforms (Windows,

becomes a tree blocker, if you break it you either have to fix it
promptly or revert right way.
