Hi Benjamin,

I implemented the BPF fix and verified it by toggling with `udev-hid-bpf remove`
and `add`: without the BPF program the UNKNOWN keyboard node appears
immediately, and with the BPF loaded it completely disappears.

I wanted to open a Merge Request on GitLab, but my new account
(@mounkastel) hit the anti-spam project limit barrier ("Limit reached:
You cannot create projects in your personal namespace"). I have filed a user
verification issue on freedesktop/freedesktop.

In the meantime, here is the git patch below so you can review or apply it
directly to udev-hid-bpf.

Cheers,
Ruzal
