cm_cxx_features: Filter out libhugetlbfs warnings

Browse Source 
Without this, CMake fails to build on Cray systems with a
craype-hugepages modulefile loaded on the front-end due to libhugetlbfs
warnings breaking the CXX Feature tests.  Filter out the warnings so the
bootstrap can proceed to successfully install CMake on Cray Linux
systems.

Fixes: #20645
