main.star: run longetst builders in presubmit if cmd/go is modified

This CL will cause longetst builders to be run if code in src/cmd/go is
modified. There are many cmd/go tests that are skipped in short mode so
only running the short tests by default leaves out a lot of coverage.

Fixes golang/go#42661
