Yonghong Song e43207fa2e tools/bpf: test btf bitfield with >=256 struct member offset
This patch modified test_btf pretty print test to cover
the bitfield with struct member equal to or greater 256.

Without the previous kernel patch fix, the modified test will fail:

  $ test_btf -p
  ......
  BTF pretty print array(#1)......unexpected pprint output
  expected: 0: {0,0,0,0x3,0x0,0x3,{0|[0,0,0,0,0,0,0,0]},ENUM_ZERO,4,0x1}
      read: 0: {0,0,0,0x3,0x0,0x3,{0|[0,0,0,0,0,0,0,0]},ENUM_ZERO,4,0x0}

  BTF pretty print array(#2)......unexpected pprint output
  expected: 0: {0,0,0,0x3,0x0,0x3,{0|[0,0,0,0,0,0,0,0]},ENUM_ZERO,4,0x1}
      read: 0: {0,0,0,0x3,0x0,0x3,{0|[0,0,0,0,0,0,0,0]},ENUM_ZERO,4,0x0}

  PASS:6 SKIP:0 FAIL:2

With the kernel fix, the modified test will succeed:
  $ test_btf -p
  ......
  BTF pretty print array(#1)......OK
  BTF pretty print array(#2)......OK
  PASS:8 SKIP:0 FAIL:0
