[LTP] [PATCH v2 1/3] lib/tst_assert: print correct file and lineno when parsing failed

[Yang Xu]

Use safe_file_scanf instead of SAFE_FILE_SCANF, so we can pass correct
file and lineno. ie prctl05.c

Before this patch, fail as below:
safe_file_ops.c:142: BROK: Failed to open FILE '/proc/self/comm1' for reading at tst_assert.c:29: ENOENT (2)

After this patch, fail as below:
safe_file_ops.c:142: BROK: Failed to open FILE '/proc/self/comm1' for reading at prctl05.c:63: ENOENT (2)
