all: add basic USB fuzzing support
This commits implements 4 syzcalls: syz_usb_connect, syz_usb_io_control,
syz_usb_ep_write and syz_usb_disconnect. Those syzcalls are used to emit USB
packets through a custom GadgetFS-like interface (currently exposed at
/sys/kernel/debug/usb-fuzzer), which requires special kernel patches.
USB fuzzing support is quite basic, as it mostly covers only the USB device
enumeration process. Even though the syz_usb_ep_write syzcall does allow to
communicate with USB endpoints after the device has been enumerated, no
coverage is collected from that code yet.
