Update the rest of golden images for theme test.

We enabled text antialiasing in NYC MR1 and so the golden images
need to be updated. ag/1522878 updated xhdpi and this CL updates
the rest of the golden images for ThemeHostTest.

Generated the following densities:
 420dpi - Nexus 5X
 560dpi - Nexus 6 (normal build)
 xxhdpi - Nexus 6 (custom build)
 xxxhdpi - Nexus 6 (custom build)
