Philippe Mathieu-Daudé c47c336e87 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. GT-64120/64120A/64121A System Controller (rev 10)
  ssh: # cat /sys/bus/i2c/devices/i2c-0/name
