Install uinput module in test image only

Browse Source 
This CL adds uinput module in INSTALL_MASK so that the module
is not installed to non-test image. A mod_image_for_test script
is implemented to install the module in the test image if the
uinput module exists.

BUG=chromium-os:26707
TEST=Build a base image and a test image. Check the directory
  /lib/modules/<version>/kernel/drivers/input/misc
where current <version> is 3.2.7.
In the base image, there should be no uinput.ko,
while in the test image, there should be uinput.ko.
