fitimage: fix name of default configuration

The new fitimage.bbclass was introduced via GitHub pullrequest [1]. There was a
small force-push which implemented a prefix for the names of the configuration
nodes to harmonize the class with the mechanism found in OE-core (see [2] & [3]).
Unfortunately it was forgotten to also apply that prefix to the name of the
configuration to utilize by default - fix that.
