Update iface.py to fix the error of Interface name

Earne · Earne · commit 703377193f4d · 2014-08-26T15:02:37.000+08:00
Sometimes, 'bytes' after 'Interface' are too long, and there is no space between 'Interface' and  'bytes'.
For example, in my /proc/net/dev there is one line begin with 'eth0:137719774170', and the iface will be identified as 'eth0:137719774170'.
