[libc-commits] [libc] [libc] Setup hdrgen for ioctl (PR #153976)

[Aiden Grossman via libc-commits]

https://github.com/boomanaiden154 created https://github.com/llvm/llvm-project/pull/153976

This patch adds some hdrgen yaml for ioctl(). Otherwise the function never actually ends up being available in a full build. This is the last thing that is needed to enable turning on LIBCXX_ENABLE_RANDOM_DEVICE.
