libbpf: Add OPTS_VALID() for log_opts in bpf_map_create
There should be an OPTS_VALID() check for log_opts before extracting its
fields.
If no such OPTS_VALID() check and an application compiled against a future
libbpf header passes a log_opts with new, non-zero fields to libbpf.so,
those fields will be ignored silently.
