minifix(CLI): only show final checksum if one exists (#692)

Browse Source 
The Etcher CLI displays a nice `Checksum: $checksum` message upon
completion. Since the addition of bmap support, a checksum for an image
might not be calculated, causing the CLI to display `Checksum:
undefined`.

This PR takes care of this small UX issue by only showing the checksum
message if one indeed exists.
