collectd: run sensors-detect in background

Browse Source 
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.

fixes #12329
