on some machines the i2c sensor search take very long time
which cause hang at first boot.
Now the search is started in background and waited for max one
minute before continue load of collectd.
On such machines collectd will not get all sensors at first startup.

This causes some i2c drivers to load and tons of error messages
being created in syslog. So we skip searching for any sensors
that do not exist.
