CI: cross-compile: riscv: Add RV64 machine with Zb* and Zk*

RISC-V already has a couple of routines to accelerate cryptographic
calculations using ISA extensions. Let's add a cross-compile target
that allows the CI to test this code.

The new defined machine is a rv64gc machine with
* all Bitmanip extensions (Zb*)
* all Scalar Crypto extensions (Zk*)

This selection matches the supported RISC-V extensions in OpenSSL.
