[PATCH] tests/acceptance/boot_linux: Skip slow Aarch64 'virt' machine TCG test

[Philippe Mathieu-Daudé]

The BootLinuxAarch64.test_virt_tcg is reported to take >7min to run.
Add a possibility to users to skip this particular test, by setting
the AVOCADO_SKIP_SLOW_TESTS environment variable:

  $ AVOCADO_SKIP_SLOW_TESTS=please make check-acceptance
  ...
    (05/88) tests/acceptance/boot_linux.py:BootLinuxAarch64.test_virt_tcg: 
SKIP: Test takes >7min
  ...
