cmd/go: delete testdata/testonly dir: it isn't being used anywhere

The TestGoBuildTestOnly test seems to be using files in testonly,
but it's actually creating different files in a tempdir GOPATH
that are completely unrelated.

Part of converting all tests to script framework to improve
test parallelism.
