From: Changqing Li <changqing.li@windriver.com>

* Add a go example recipe with cgo enabled, Flush the stdio buffer so
  that piped stdout can read the output before the program exits.

  This is for covering go reproducibility with cgo enabled. The test
  coverage is provided by the reproducibility world build.

  Related to the following commit [1]:
  [0642d23230 go.bbclass: change GOTMPDIR to improve reproducibility]

* cgo-helloworld is a complement for go-helloworld, also add it in
  runtime case for go and gotools
