tools/nolibc: stackprotector: Avoid stalling program startup if crng is not init yet

We are using the getrandom syscall to get a random seed for the
stack protector canary but we are calling it with no flags which means
it'll block until there is some real randomness to return.

This means that if the crng is not ready yet program startup will
block and if you are unlucky that could be for a long time and
look like the program has crashed.

Even if the call to getrandom does not yield any random data,
we will still initialize the canary.
