[PATCH v2] tests/acceptance/machine_sparc_leon3: Do not run HelenOS test by default

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

The www.helenos.org server is slow and downloading the Leon3 binary
takes too long [*]. Do not include this test in the default suite.

Similarly to commit 471c97a69b:

  Currently the Avocado framework does not distinct the time spent
  downloading assets vs. the time spent running a test. With big
  assets (like a full VM image) the tests likely fail.

  This is a limitation known by the Avocado team.
  Until this issue get fixed, do not run this tests automatically.

  Tests can still be run setting the AVOCADO_TIMEOUT_EXPECTED
  environment variable.
