warp7: hab: Set environment variable indicating HAB enable

Browse Source 
This patch adds an environment variable called "hab_enabled" which gets set
to a boolean status indicating whether HAB is enabled or not.

Subsequent patches can use this environment variable to determine if its
necessary to run a given binary through the hab_auth_img console command.
