BootLinuxSshTest: Test some userspace commands on Malta

This tests boot a full VM and check the serial console until the SSH daemon is running, then start a SSH session and run some commands. This test can be run using: $ avocado --show=ssh run -t arch:mips tests/acceptance/linux_ssh_mips_malta.py ssh: Entering interactive session. ssh: # uname -a ssh: Linux debian-mips 3.2.0-4-4kc-malta #1 Debian 3.2.51-1 mips GNU/Linux ssh: # lspci -d 11ab:4620 ssh: 00:00.0 Host bridge: Marvell Technology Group Ltd.
