We also need coverage for when the malicious user is not using the
proper ioctls definitions and tries to work around the driver.
Most of the scaffholding has been generated by claude-4-sonnet and then
carefully reviewed.

Try to ensure all ioctls are having at least one test.

This will be useful to introduce variants in tests to test the
interactions between HID-BPF and some kernel modules.

Allows to have an abstract class uhid_device which handles all of the
uhid part without having to mess up with individual fds.
struct attach_prog_args is now never used in hid_bpf.c, so drop it as well

Add 4 tests for the new revoke ioctl, for read/write/ioctl and poll.

Largely inspired from hid_bpf.c for the fixture setup.
Create a couple of tests for hidraw:
- create a uhid device and check if the fixture is working properly
- inject one uhid event and read it through hidraw
These tests are not that useful for now, but will be once we start adding
the ioctl and BPFs to revoke the hidraw node.
