linux: fix unused code warning without gpu feature

When the gpu feature is not enabled, the compiler warns about unused
imports of DEFAULT_TOUCH_DEVICE_HEIGHT and DEFAULT_TOUCH_DEVICE_WIDTH.
Put these imports behind a cfg check to silence the warning.

BUG=None
TEST=cargo build
TEST=emerge-nami crosvm # test with gpu feature enabled
