bc82f83298 Auto merge of #884 - Aaron1011:fix/linux-getrandom, r=RalfJung 
Allowing passing a null pointer to getrandom() when length is 0

The Linux kernel will handle a null pointer passed to 'getrandom'
without error, as long as the length is also 0. The `getrandom` crate
relies on this behavior: ab44edf3c7/src/linux_android.rs (L26)

Since it works fine on the actual kernel (and should continue to, due to
the kernel's backwards-compatibility guarantees), Miri should support it
as well.

Do nothing when we try to generate random data of length 0 
This preserves compatibility with programs that pass a null pointer and
a length of zero to getrandom(), or their platform's equivalent.
