misc/cgo/{life,stdio}: remove reliance on test/run.go
The misc/cgo/life and misc/cgo/stdio tests started out as fairly simple
test cases when they were added, but the machinery to execute them has
grown in complexity over the years.
They currently reuse the test/run.go runner and its "run" action without
needing much of the additional flexibility that said runner implements.
Given that runner isn't well documented, it makes it harder to see that
ultimately these tests just do 'go run' on a few test programs and check
that the output matches a golden file.
Maybe these test cases should move out of misc to be near similar tests,
or the machinery to execute them can made available in a package that is
easier and safer to reuse. I'd rather not block the refactor of the test
directory runner on that, so for now rewrite these to be self-contained.
Also delete misc/cgo/stdio/testdata/run.out which has no effect on the
test. It was seemingly accidentally kept behind during the refactor in
CL
6220049.
For #56844.
