Rob Bradford c1be41bfbf net_util: Replace use of rand crate with libc::getrandom() ...

The rand crate provides a full cross platform true cryptographic random
number implementation. As such it brings it lots of othe dependencies
and increases our binary size and compile time. This is excessive for
generating a MAC address.

From the cargo tree output:

│   │   ├── rand v0.8.3
│   │   │   ├── libc v0.2.86
│   │   │   ├── rand_chacha v0.3.0
