Add alt_system_info table

[korylprince]

This PR adds the alt_system_info table, which mimics the built-in system_info table.

The table avoids the Allow "osquery" to find devices on local networks? prompt that the built-in system_info table triggers on macOS 15.0.

On versions other than 15.0, this table queries and returns the output of the system_info table.

The cpu_subtype field always returns empty with this table, because it requires the use of C APIs (e.g. CGo) to fetch.

The following code will allow someone to get the cpu_subtype field, if they want to deal with CGo:

/*
#include <mach/mach.h>

struct cpu_type_info_t {
	char *cpu_type;
	char *cpu_subtype;
};

struct cpu_type_info_t getCpuTypeInfo() {
  struct cpu_type_info_t cpu_info;
  int host = mach_host_self();

  host_basic_info_data_t host_data;
  mach_msg_type_number_t count = HOST_BASIC_INFO_COUNT;
  if (host_info(host, HOST_BASIC_INFO, (host_info_t)&host_data, &count) !=
      KERN_SUCCESS) {
    return cpu_info;
  }

  // Get human readable strings
  slot_name(host_data.cpu_type, host_data.cpu_subtype, &cpu_info.cpu_type, &cpu_info.cpu_subtype);

  return cpu_info;
}
*/
import "C"

func GetCPUInfo() (cpuType, cpuSubtype string) {
	info := C.getCpuTypeInfo()
	cpuTypePtr := (*C.char)(unsafe.Pointer(info.cpu_type))
	cpuSubtypePtr := (*C.char)(unsafe.Pointer(info.cpu_subtype))
	return C.GoString(cpuTypePtr), C.GoString(cpuSubtypePtr)
}

Example from macOS 15.0:

osquery> select * from system_info;

Thank you for this - have you considered moving the osquery client in the sofa table to your new generic one as well?
