beam_lib, cover: Don't crash when an abstract code backend is missing
On a computer without Elixir installed, `beam_lib` would crash when
asked to retrieve the abstract code for a BEAM file produced by the
Elixir compiler. Instead of crashing when the backend module is
missing, return `{error,{missing_backend,BeamFile,Backend}}`.
Also update `cover` to handle the new error from `beam_lib`.
Resolves #4353
