internal/syscall/unix: allow calling getrandom(..., 0, ...)
Calling getrandom() with a zero length is actually valid and useful:
- Calling getrandom(..., 0, 0) will block until the RNG is initialized.
- Calling getrandom(..., 0, GRND_NONBLOCK) will query whether the RNG
is initialized.
So instead of short circuiting execution for these circumstances, pass
this through to the syscall.
