Fix format error for sioUtil-UT

**What this PR does / why we need it**:
1、Use t.Fatalf instead of t.Fatal when format is needed;
2、Before my change, when open file failed you will get such return "failed to open conf file: %!(EXTRA os.file=&{***})". After my change, when open file failed you will get such return "Failed to open conf file: /dir/filename",which is more human readable .
