[PATCH 1/3] tests/functional: Add QemuUserTest class

[Philippe Mathieu-Daudé]

Per commit 5334df4822 ("tests/avocado: Introduce
QemuUserTest base class"):

  Similarly to the 'System' Test base class with methods
  for testing system emulation, the QemuUserTest class
  contains methods useful to test user-mode emulation.
