Fix fetching data for interfaces with a dash in the name

Browse source 
munin-node passes the original interface name (as extracted from
/proc/net/dev) to if_* and if_err_*. Thus replacing dash with underscore
results in interfaces not being found anymore.

Source: patch "220-modify-ifname-parser" from OpenWrt
