Add check_ksm_numa_merge() function to test that pages in different NUMA nodes are being handled properly. First, two duplicate pages are allocated in two separate NUMA nodes using the libnuma library. Since there is one unique page in each node, with merge_across_nodes = 0, there won't be any shared pages. If merge_across_nodes is set to 1, the pages will be treated as usual duplicate pages and will be merged. If NUMA config is not enabled or the number of NUMA nodes is less than two, then the test is skipped. The test is run as follows: ./ksm_tests -N
