selftests/bpf: Select NUMA_NO_NODE to create map

[ Upstream commit 4107a1aeb20ed4cdad6a0d49de92ea0f933c71b7 ]

On powerpc, a CPU does not necessarily originate from NUMA node 0.
This contrasts with architectures like x86, where CPU 0 is not
hot-pluggable, making NUMA node 0 a consistently valid node.
This discrepancy can lead to failures when creating a map on NUMA
node 0, which is initialized by default, if no CPUs are allocated
from NUMA node 0.

This patch fixes the issue by setting NUMA_NO_NODE (-1) for map
creation for this selftest.
