deprecate pkg/loopback (utility package for devicemapper)

Browse source 
This package was introduced in af59752712
as a utility package for devicemapper, which was removed in commit
dc11d2a2d8 (v25.0.0).

It looks like there's no external consumers of this package, so we should
consider removing it, but deprecating it first, just in case.
