Subject: [PATCH] fix check_mk_agent.openbsd multi network interfaces support

current behaviour: the script work well if there is only
one network interface configured but as soon as more then
one network interface exists the reports just garbage.

the cause: seeting IFS to '' will skip any substitution
resulting in for loop only executing once (the list to
iterate over just consists of a single value)

solution: set IFS to only contain a newline
