target/riscv: Only build KVM guest with same wordsize as host
Per Anup Patel in [*]: > Currently, we only support running rv64 guest on rv64 host > and rv32 guest on rv32 host. > > In the future, we might support running rv32 guest on rv64 > host but as of now we don't see a strong push for it. Therefore, when only using the KVM accelerator it is pointless to build qemu-system-riscv32 on a rv64 host (or qemu-system-riscv64 on a rv32 host). Restrict meson to only build the correct binary, avoiding to waste ressources building unusable code.
