[PATCH-for-5.0 4/8] tests/acceptance/machine_sparc_leon3: Disable HelenO

Subject: [PATCH-for-5.0 4/8] tests/acceptance/machine_sparc_leon3: Disable HelenOS test

From: Philippe Mathieu-Daudé <address@hidden>

This test was written/tested around beginning of 2019, but was
extracted from a bigger series and posted end of June 2019 [*].
Unfortunately I did not notice commit 162abf1a8 was merged by
then, which implements the AHB and APB plug and play devices.

HelenOS 0.6 is expecting the PnP registers to be not implemented
by QEMU, then forces the discovered AMBA devices (see [2]).

Before 162abf1a8, the console was displaying:

As of this commit, it is now confused:

  ABMA devices:
  <1:3000> at 0x00000000 irq 0
  <1:3000> at 0x00000000 irq 0
  <1:3000> at 0x00000000 irq 0

  <1:3000> at 0x00000000 irq 0
  <1:3000> at 0x00000000 irq 0

As this test is not working as expected, simply disable it (by
skipping it) for now.
