bpf: support access variable length array of integer type
After this commit:
bpf: Support variable length array in tracing programs (9c5f8a1008a1)
Trace programs can access variable length array, but for structure
type. This patch adds support for integer type.
Example:
Hook load_balance
struct sched_domain {
...
unsigned long span[];
}
