test: host_command_fuzz: fuzzing test
Writing fuzzing tests is a little tricky, as clang takes over the main
function. Instead, we start the test main function in a thread, and
have LLVMFuzzerTestOneInput prepare the host command buffer, and
wake the TEST_RUNNER task.
To make fuzzing faster, we only send somehow correctly formed requests,
with a valid checksum and length (this can be disabled with an option).
We also make sure that the emulator does not hibernate, reboot or jump
to a different image when fuzzing is enabled.
