cheets: switch arc wallpaper layout to CENTER_CROPPED.

Android wallpapers seem to be always center cropped that
when wallpaper dimensions differ from the current
workspace dimensions, it resizes to fill the screen
while preserving aspect ratio and letting part of it to
be cropped. This avoids bugs like b/31653316.

BUG=642465
Test=Setting wallpaper functions as expected.
