cmd/dist: delete moved_goroot test
This test is largely obviated by the goroot_executable and
list_goroot_symlink cmd/go script tests. It's the last user of several
special-case features in cmd/dist and runs only under a fairly
constrained set of conditions (including only running on builders, not
locally). Delete it.
