In order to automate certificate issuance and renewal for Raspberry Pi devices, we need aarch64 builds of the `sshca` tool. Using the `matrix` feature of Jenkins pipelines lets us reuse the same stage definition for building the client on both platforms. Unfortunately, the `matrix` block has to encompass the server stage as well, as `matrix` cannot be nested below `parallel`, and we don't want to build the server and clients sequentially. This makes the code a bit less clear, as the server and client stages are now conditional based on the matrix intersection, but it is cleaner than duplicating the entire client stage.
