[BUG] Compile modern_bpf error

[yzewei]

Describe the bug make drivers_test

/home/yzw/rd/libs/driver/modern_bpf/helpers/extract/extract_from_kernel.h:648:49: error: member reference base type 'struct percpu_counter[4]' is not a structure or union
  648 |                 BPF_CORE_READ_INTO(&swap_entries, mm, rss_stat.count[MM_SWAPENTS].counter);
      |                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~

The code files involved include : modern_bpf/programs/tail_called/events/syscall_dispatched_events/execve.bpf.c modern_bpf/programs/tail_called/events/syscall_dispatched_events/execveat.bpf.c modern_bpf/helpers/extract/extract_from_kernel.h

How to reproduce it First judge the kernel version, and then execute the corresponding operation. like this:

#if LINUX_VERSION_CODE >= KERNEL_VERSION(6, 3, 0)

instead of

if(bpf_core_field_exists(((struct kernel_cap_struct *)0)->cap)){...}

Expected behaviour
