Move the test runner to a higher DPI screen. (flutter/engine#3688)

Browse Source 
Having the device pixel ratio of the test shell be 1.0x makes it
unlikely that we will catch errors relating to mishandling of the
device pixel ratio in the test shell.

This patch arbitrarily increases the device pixel resolution while
keeping the logical resolution the same.
