fix ping output of ltpClient with dump-like format

Hi, everyone I found the testcases/network/sockets/ltpClient ping output is messy. And that made my uncomfortable. So I fix it with dump-like format. output before the fixing:

[0]:  [69] [0] [0] [84] [230] [245] [0] [0] [64] [1] [107] [54] [9] [41] [11] [22]
[16]:  [9] [41] [11] [22] [0] [0] [236] [161] [208] [108] [7] [0] [48] [49] [50] [51]
[32]:  [52] [53] [54] [55] [56] [57] [58] [59] [60] [61] [62] [63] [64] [65] [66] [67]

[64]:  [84] [85] [86] [87] [88] [89] [90] [91] [92] [93] [94] [95] [96] [97] [98] [99]
[80]:  [100] [101] [102] [0]

output after the fixing:

[ 0]:   45  00  00  54  bf  b3  00  00  40  01  92  78  09  29  0b  16

[80]:   64  65  66  00

here is the patch:

         }

         printf("\n");

Hope it will be merged. :)

Thanks.
