  1. Add RNG for Fortanix SGX 

    Currently, ring doesn't provide a random number generator for SGX at all.
This is probably by accident, but is, in fact, the correct behavior.

Due to distrust of the OS, SGX enclave applications need a source of
randomness that is not forgable by the OS. This pretty much leaves only
the RDRAND instruction. Fortunately, Rust provides an intrinsic for this
instruction.
