[PULL 38/44] tests/acceptance: Add MIPS record/replay tests

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

From: Pavel Dovgalyuk <pavel.dovgalyuk@ispras.ru>

This patch adds MIPS-targeted acceptance tests for
record/replay functions.

Message-Id: <160276110297.2705.10918105269658307206.stgit@pasha-ThinkPad-X280>
[PMD: Moved 'override timeout' comment from instance to class,
      moved nanomips tests to ReplayKernelSlow class,
      tagged ReplayKernelSlow class with AVOCADO_TIMEOUT_EXPECTED]
