Put everything in one function because each trap … EXIT overwrites the
previous definition.
Call set +e at the beginning so that we don't exit prematurely before
all of the cleanup operations have been run.
Unset the FOG_RC variable when we're done with it. Shouldn't make a
different to the caller shell, but better safe than sorry and it's
consistent with the other scripts like this.
Remove the comment now that cleanup() is doing more than just deleting
the temporary FOG_RC file.
