  -----------
  [libc][semaphore] Zero-initialize rand_bytes to fix GCC warning (#195757)

GCC 15 warns about `rand_bytes` being maybe uninitialized when passed to
`getrandom`. Since `getrandom` writes to it, it doesn't strictly need
initialization, but zero-initializing it satisfies the compiler and
avoids the `-Werror=maybe-uninitialized` error.

Fix for https://github.com/llvm/llvm-project/pull/192278
