    lib/oeqa/selftest/cases/gotoolchain: add selftest for the Go toolchain
    
    Add a simple test case to being testing of the Go toolchain:
    1) build meta-go-toolchain
    2) create a temp directory and install the generated Go toolchain within
    3) fetch an archive of the Go Dep tool
    4) create an appropriately laid out GOROOT and inflate the dep archive there
    5) build the dep command with the SDK's Go toolchain and check it returned
       successfully.
