LU-2800 autoconf: remove topology checks

LU-2800 autoconf: remove topology checks

The topology API has been stable since 2.6.32, so we don't need to
check for it anymore.

The options defined by a series of tests in LC_EXPORT_NODE_TO_CPUMASK
and LC_EXPORT_CPUMASK_OF_NODE look like this:
HAVE_CPUMASK_OF_NODE=1 since v2.6.29
HAVE_NODE_TO_CPUMASK=0 since v2.6.29
HAVE_CPUMASK_COPY=1 since v2.6.28
HAVE_CPUMASK_SIZE=1 since v2.6.28
HAVE_TOPOLOGY_THREAD_SIBLINGS=0 since v2.6.32
HAVE_TOPOLOGY_CORE_SIBLINGS=0 since v2.6.32
HAVE_TOPOLOGY_THREAD_CPUMASK=1 since v2.6.30
HAVE_TOPOLOGY_CORE_CPUMAS=1K since v2.6.30
HAVE_CPU_TOPOLOGY=1 since v2.6.12

Let's eliminate all those tests and remove the dead code.
