It would be useful to get the stderr from the failing process. 🤔

Looks like this test was added in https://go.dev/cl/372798 for #38824.

cmd/cgo/internal/testplugin: simplify TestForkExec and log stderr output
0c13bd6 
This test used to run with a separate goroutine for timeout behavior,
presumably because it was difficult to set an appropriate timeout.

Now that the test is in cmd instead of misc, we can use
internal/testenv.Command, which makes adding the test timeout much
simpler and eliminates the need for the explicit goroutine.

For #61846.

@bcmills Thanks for working on that CL! Are we now just waiting for another failure? Added WaitingForInfo if so, but feel free to drop it.

Yeah, I think at this point it's fine to just wait — if it's a frequent failure we should get a more detailed log soon, and if it's not then it's probably not important to go chasing after.
