Add FilesApp VolumeMetadata.remoteMountPath

VolumeMetadata.remoteMountPath is the path on the remote host where this
volume is mounted, for crostini this is the user's homedir
(/home/<username>).

The remoteMountPath will be used in crostini trash to prefix Path in
*.trashinfo files so that paths reflect the valid local path, and our
trash interactions can interoperate with other linux file managers.
