refactor: get rid of is-elevated
(#1262)
This commit implements our own version of the `is-elevated` module. The reason behind this is that `is-elevated` relies on lots of unnecessary modules, that eventually require `spawn-sync` and `try-thread-sleep`, which conditionally require dependencies that are not even declared in their `package.json`, causing issues when concatenating the Etcher CLI. See: https://github.com/resin-io/etcher/pull/1235 See: https://github.com/resin-io/etcher/pull/1228 Signed-off-by: Juan Cruz Viotti <jviotti@openmailbox.org>
