selftests/net: Fix reuseport_bpf_numa by skipping unavailable nodes
In some platforms the numa node numbers are not necessarily consecutive,
meaning that not all nodes from 0 to the value returned by numa_max_node()
are available on the system. Using node numbers which are not available
results on errors from libnuma such as:
---- IPv4 UDP ----
send node 0, receive socket 0
libnuma: Warning: Cannot read node cpumask from sysfs
./reuseport_bpf_numa: failed to pin to node: No such file or directory
Fix it by checking if the node number bit is set on numa_nodes_ptr, which
is defined on libnuma as "Set with all nodes the kernel has exposed to
userspace".
