fix(CLI): check CLI elevation early on (#864)

Browse Source 
The CLI requires elevation permissions to actually be able to write to
drives. For this reason, it makes sense that we introduce such a check
early on.

See: https://github.com/resin-io/etcher/issues/726
Change-Type: patch
Changelog-Entry: Check available permissions in the CLI early on.
