gpu_display: Don't include linux kernel headers

Browse source 
This makes it easier to integrate crosvm into Android (which doesn't
have the kernel headers available for all the build targets crosvm is
needed in).

The BTN_LEFT constant is already hardcoded in virtio/input/constants.rs,
so the additional tech debt seems acceptable.

BUG=b:228881829
TEST=cargo build && cargo test
