feat(CLI): validate drive (#587)

Browse Source 
The Etcher CLI doesn't care if the drive exists or not. The user will
eventually find out since the CLI will output an `ENOENT` when trying to
actually write data, however its nicer from a UX perspective to catch
this early on.

Change-Type: minor
Changelog-Entry: Validate the existence of the passed drive.
