[PATCH v4 7/7] tests/avocado: Add an avocado test for riscv64

[LIU Zhiwei]

From: TANG Tiancheng <tangtiancheng.ttc@alibaba-inc.com>

To regularly test booting Linux with rv32 on QEMU RV64,
we have added a test to boot_linux_console.py to retrieve
cpuinfo and verify if it shows 'rv32' when using RV64 to
boot rv32 CPUs.
