Increase max distance for folder creation for tablets.

Tablets generally have larger cell sizes (relative to phones, and relative to
the icon sizes with the cells). By increasing the distance from 55% to 75% of
icon size, it is easier for users to meet the folder creation threshold before
the icon reorder timeout is triggered.
