Disable eject button for StubVolumes

StubVolumes are managed from outside Android (e.g. Chrome OS). So, they
should not be unmounted via the eject button in DocumentsUI.

Bug: 187111763
Test: (Tested in R) Manually check and confirm that the eject button is
      not shown for mounted StubVolumes.
