[PATCH v2 4/5] app/proc-info: adjust the display format of RSS info

[Jie Hai <haijie1@huawei.com>]

This patch splits the length and value of RSS key into two parts,
removes spaces between RSS keys, and adds line breaks between RSS
key and RSS hf.

Before the adjustment, RSS info is shown as:
  - RSS
	  -- RSS len 40 key (hex): 6d 5a 56 da 25 5b e c2 41 67 \
	     25 3d 43 a3 8f b0 d0 ca 2b cb ae 7b 30 b4 77 cb 2d \
	     a3 80 30 f2 c 6a 42 b7 3b be ac 1 fa -- hf 0x0
and after:
  - RSS info
	  -- RSS key len : 40
	  -- RSS key (hex) :
		6d5a56da255b0ec24167253d43a38fb0d0ca2bcbae7b30b4 \
		77cb2da38030f20c6a42b73bbeac01fa
	  -- RSS hf : 0x0
