selftests/bpf: Call bpf_get_numa_node_id() in trigger_count()
The bench test "trig-kernel-count" can be used as a baseline comparison
for fentry and other benchmarks, and the calling to bpf_get_numa_node_id()
should be considered as composition of the baseline. So, let's call it in
trigger_count(). Meanwhile, rename trigger_count() to
trigger_kernel_count() to make it easier understand.
