Enable Canvas/draw-static-canvas-2d-to-hw-accelerated-canvas-2d.html

This perf test is disabled in r176467, but I enable for two reasons;
1. draw-dynamic-canvas-2d-to-hw-accelerated-canvas-2d.html is almost same to
this test. If this test should be disabled, dynamic test should be also
disabled.
2. I cannot reproduce on Nexus 5.

I'll track if this change causes Nexus 10 timeout again.
