cmd/go: report an error for 'go list -m ...' outside a module

Previously, we just reported an error for "all". Now we report an
error for any pattern that matches modules in the build list. The
build list can only contain the module "command-line-arguments", so
these patterns are not meaningful.

Fixes #35728
