[Ｖ字龍(Vdragon)]

Currently ucimf scans IMF modules in /usr/lib/<arch>/ucimf, however ucimf-chewing installs libraries in /usr/lib/ucimf, letting ucimf not found the module:

```
[DEBUG]:IMF Modules scan path: /usr/lib/i386-linux-gnu/ucimf/
[DEBUG]: Load Module[ 1 ]: dummy.so
[DEBUG]:UCIMF core intialized.
```
