I'm OK with the change, but given that it's a simple redirecting header which will likely never be more than a single `#include` statement, do we need a comment and header guards, or we can simply do a one-liner like we've done for https://github.com/llvm/llvm-project/blob/main/libc/include/syscall.h ?
