Several tests unmount then re-mount the scratch filesystem, to check
that the content is unchanged; but unmounting a tmpfs is designed to
lose its content, which causes such tests to fail unnecessarily. Add
_scratch_remount(), which instead uses remount on a tmpfs to preserve
its contents. Also add _test_remount() to do the same for the test
device.
