test: add a test for the ILTEK TP touchscreen
A special device that cannot handle a GET_FEATURE request correctly, it interprets that as a switch mode command. So our test merely creates the device and asserts if GET_FEATURE is run on this device.
Because hid-multitouch will run GET_FEATURE for Contact Max and the Win8 blob, we mangle the report descriptor a bit. This way we can be sure GET_FEATURE isn't run on this device unless the kernel bug is present.
For the kernel fix see: https://patchwork.kernel.org/patch/11550115/
