[LTP] [PATCH v2] nm01: Remove prefix zeros of the addresses output by nm before comparing

[zhe.he@windriver.com]

From: He Zhe <zhe.he@windriver.com>

The latest nm v2.33.1.20191208 outputs symbols addresses without prefix zeros
for "nm -f posix", which causes the following error.
nm01 5 TFAIL: Got wrong format with -f bsd

Let's remove the prefix zeros before comparing.

v2:
Add boundary mark to RE pattern to exactly cover the prefix zeros
Add one more temp file to contain trimmed output
