in scripts/Makefile.clang.

Now that we have a proper selftests/hid kernel entry and that the tests
are more reliable, it is time to directly include those in the kernel
tree.

This one gets skipped when run by vmtest.sh as we currently need to test
against actual kernel modules (.ko), not built-in to fetch the list
of supported devices.

There are a lot of multitouch tests, and the default timeout of 45 seconds
is not big enough. Bump it to 200 seconds.

I haven't imported all of hid-tools, the python module, but only the
tests related to the kernel. We can rely on pip to fetch the latest
hid-tools release, and then run the tests directly from the tree.

This should now be easier to request tests when something is not behaving
properly in the HID subsystem.

Unfortunately this is not the case and we need to manually call that step.

selftests: add tests for the HID-bpf initial implementation

The tests are pretty basic:
- create a virtual uhid device that no userspace will like (to not mess
up the running system)
- attach a BPF prog to it
- open the matching hidraw node
- inject one event and check:
* that the BPF program can do something on the event stream
* can modify the event stream
- add another test where we attach/detach BPF programs to see if we get
errors

Note: the Makefile is extracted from selftests/bpf so we can rebuild
the libbpf and bpftool components from the current kernel tree without
relying on system installed components.
