Fix this file to the point that "go get" on gyuho/goraph works.

⇒  go get github.com/gyuho/goraph/...
package github.com/gyuho/goraph/...
        imports github.com/gyuho/goraph/algorithm/scc/kosaraju
        imports github.com/gyuho/goraph/algorithm/scc/kosaraju:
/usr/local/google/home/samschaevitz/gocode/src/github.com/gyuho/goraph/algorithm/scc/kosaraju/kosaraju_test.go:93:4: expected 'package', found 'EOF'
