Bryan C. Mills f36c7c5983 cmd/go: traverse module-root symlinks in Walk calls
fsys.Walk, like filepath.Walk, avoids traversing symlinks. Also like
filepath.Walk, it follows a symlink at the root if the root path ends
in a file separator (consistent with POSIX pathname resolution¹).

If the user's working directory is within a repository stored in
(and symlinked to) a different filesystem path, we want to follow the
symlink instead of treating the module as completely empty.
