set_mempolicy: require CONFIG_NUMA

On kernels without CONFIG_NUMA=y set_mempolicy() returns ENOSYS,
which the test misreports as TFAIL.

set_mempolicy05.c:105: TFAIL: set_mempolicy should fail with EFAULT or EINVAL, instead returned 38

remaining of these tests (set_mempolicy[01-04]) checks for minimum two
NUMA nodes and reports TCONF, but those also should exit on CONFIG_NUMA
check.

tse_numa.c:200: TINFO: Found 1 NUMA memory nodes
tse_numa.c:141: TINFO: File '/sys/devices/system/node/node0/meminfo' does not exist! NUMA not enabled?
get_mempolicy02.c:60: TCONF: test requires at least one NUMA memory node

Add .needs_kconfigs with CONFIG_NUMA=y
