linux-user: Fix struct statfs ABI on loongarch64
Previously the 32-bit version was incorrectly chosen, leading to funny
but incorrect output from e.g. df(1). Simply select the version
corresponding to the 64-bit asm-generic definition.

For reference, this program should produce the same output no matter
natively compiled or not, for loongarch64 or not:

```c
#include <stdio.h>
#include <sys/statfs.h>

int main(int argc, const char *argv[])
{
  struct statfs b;
  if (statfs(argv[0], &b))
    return 1;

  printf("f_type = 0x%lx\n", b.f_type);
  printf("f_bsize = %ld\n", b.f_bsize);
  printf("f_blocks = %ld\n", b.f_blocks);
  printf("f_bfree = %ld\n", b.f_bfree);
  printf("f_bavail = %ld\n", b.f_bavail);

  return 0;
}

// Example output on my amd64 box, with the test binary residing on a
// btrfs partition.

// Native and emulated output after the fix:
//
// f_type = 0x9123683e
// f_bsize = 4096
// f_blocks = 268435456
// f_bfree = 168406890
// f_bavail = 168355058

// Output before the fix, note the messed layout:
//
// f_type = 0x10009123683e
// f_bsize = 723302085239504896
// f_blocks = 168355058
// f_bfree = 2250817541779750912
// f_bavail = 1099229433104
```
