  [VFS] Use original path when falling back to external FS

This is a follow up to 0be9ca7c0f9a733f846bb6bc4e8e36d46b518162 to make
paths in the case of falling back to the external file system use the
original format, preserving relative paths, and allow the external
filesystem to canonicalize them if needed.
