cmd/go: add a 'buildmode' condition for script tests
In CL 208233 I am fixing a panic that occurs only with a specific
build mode. I want that test to run on all platforms that support that
build mode, but the logic for determining support is somewhat
involved.
For now, I am duplicating that logic into the cmd/internal/sys
package, which already reports platform support for other build flags.
We can refactor cmd/go/internal/work to use the extracted function in
a followup CL.
Updates #35759
