Disable integration tests on AVX platforms
Due to a small difference in FT counters (which in this MR is worked around by a LineSkipper
in the boole-FT
test), all integration tests are failing on AVX platforms with large stdout diffs
Since all AVX functionality is tested in the individual sub-detector tests, the problem can be worked around by disabling the integration tests on AVX platforms.
