fff-hoods: Do not run configurehood and nodewatcher at the same time

nodewatcher and configurehood have both been run with */5 in micrond.

This may lead to nodewatcher accessing information just being
changed by configurehood. To prevent this, we just change the
start of configurehood, as this has no known disadvantages.

A change of the nodewatcher start would also solve the problem,
but nodewatcher is synchronized to the alfred-master and the
Monitoring.

Fixes #96.
