Fix import ordering from the move from hcl2 repository

When we did the automatic rewriting from the hashicorp/hcl2 import paths
to hashicorp/hcl/v2 import paths, our automatic rewrite script did not
run "go fmt" afterwards and so left some imports misordered as a result
of the slightly-differently-shaped directory structure in the new
repository.
