[PATCH v3 20/26] tests/avocado: disable sh4 rd2 tests on Gitlab

["Alex Bennée" <alex.bennee@linaro.org>]

Running repeated invocations on a number of test boxes show a fairly
high error rate:

  $ retry.py -n 100 -c -- ./tests/venv/bin/avocado run tests/avocado/boot_linux_console.py:BootLinuxConsole.test_sh4_r2d
  retry.py called with ['./tests/venv/bin/avocado', 'run', 'tests/avocado/boot_linux_console.py:BootLinuxConsole.test_sh4_r2d']
  Results:
  Run, Ret, Pass/Fail, Time, Total Pass, Total Run
  ...
  Results summary:
  0: 94 times (94.00%), avg time 2.254 (0.00 varience/0.04 deviation)
  1: 3 times (3.00%), avg time 1.837 (0.02 varience/0.14 deviation)
  8: 3 times (3.00%), avg time 91.288 (0.02 varience/0.15 deviation)

Examining the logs they fall into various categories of un-handled
unaligned access by user space and unexpected FPU usage by the kernel
which ultimately lead to the failure to reach the login prompt. This
could be bugs in the translator that only get hit occasionally or just
a flaky kernel - its hard to tell. To avoid these failures gating CI
lets skip on GitLab.
