Bryan C. Mills 8f1e2d4ef7 misc/cgo/testsanitizers: move test source files into testdata directory
If we run 'go test ./...' in the misc module, we don't want to see
errors for these standalone files.

We could instead add +ignore tags to each file individually, but this
is exactly what a testdata directory is for.

Updates #30228
