  [VirtualFileSystem] Add unit test for vfs::YAMLVFSWriter

Add a unit test for vfs::YAMLVFSWriter.

This patch exposes an issue in the writer: when we call addFileMapping
with a directory, the VFS writer will emit it as a regular file, causing
any of the nested files or directories to not be found.
