The test attempted to find all stdlib packages by scanning
pkg/$GOOS_$GOARCH for .a files and then tried to import all of them.
Now that .a files are no longer being placed there, the test is a
noop. Fix this by using go list std (and filtering out testonly
packages) and trying to import all of those to recreate what the test
intended to do.
This also removes a dependency on the pkg/$GOOS_$GOARCH directory
which will stop being produced by dist in CL 453496.
For #47257
