fs: do not descend into symlinks for ** unless following symlinks

[RafaelGSS]

fs.glob(), fs.globSync(), and fs.promises.glob() descended into symlinked directories for globstar patterns even when followSymlinks was false. Restrict globstar recursion to directories so the default behavior and an explicit false value do not traverse symlink targets.
