Fix mock-fs test failure caused by broken symlinks

Add cleanup function to remove broken symlinks in node_modules before
loading with mock-fs. This prevents ENOENT errors when mock-fs tries
to stat broken symlinks during directory traversal.

The broken symlinks were in @socketbin packages pointing to non-existent
directories, which caused mockFs.load() to fail.
